Things to Do in Orlando in September (2026): Family Fun, Aquarium Adventures and More

September 2026 in Orlando brings the best of several seasons together. Summer vacation crowds begin to ease, families can still enjoy plenty of sunshine, and the first signs of Halloween start appearing around Central Florida.

If you are planning an Orlando vacation in September, there are plenty of ways to fill your itinerary beyond the major theme parks. From indoor attractions and family friendly activities to seasonal events, International Drive entertainment and Halloween experiences, September is a great time to explore more of Orlando.

One attraction that belongs on a September itinerary is SEA LIFE Orlando Aquarium at ICON Park. Located on International Drive, this fully indoor aquarium offers an easy way to explore marine life while staying comfortable during Florida's unpredictable September weather. Guests can discover sharks, rays, sea turtles, jellyfish and thousands of other sea creatures while exploring Florida's only 360 degree ocean tunnel. 

And for adults looking for a unique Orlando night out, September also brings Fins & Flights, an after hours aquarium experience featuring craft beer and marine life.

Here are some of the best things to do in Orlando in September:

Quick Guide to Things to Do in Orlando in September (2026)

1. Explore SEA LIFE Orlando Aquarium

When you are deciding what to do in Orlando in September, an indoor attraction can be one of the smartest additions to your itinerary.

September is still part of Florida's rainy season, which means a sunny morning can occasionally turn into an afternoon shower. SEA LIFE Aquarium Orlando provides an opportunity to keep exploring without letting the weather dictate your plans.

Located at ICON Park on International Drive, SEA LIFE Orlando is home to more than 5,000 sea creatures across nine themed zones and spans more than 25,000 square feet. The aquarium's exhibits include sharks, rays, sea turtles, jellyfish and other fascinating marine life. 

One of the highlights is Florida's only 360 degree ocean tunnel. Instead of simply looking into an aquarium exhibit, guests can walk through an underwater environment surrounded by marine life.

For families visiting Orlando with kids, there are also interactive experiences where young explorers can get closer to the natural world. The aquarium features a touchpool where guests can encounter friendly sea stars and other creatures while learning more about ocean habitats. 

Why SEA LIFE Orlando is a great September activity

September is a particularly good month to include indoor attractions in an Orlando itinerary because they give you flexibility.

You can visit SEA LIFE Orlando in the morning, during a rain shower or as part of a larger International Drive day. Since the aquarium is located at ICON Park, it is also easy to combine your visit with other attractions, restaurants and entertainment.

For families, that flexibility can make a big difference.

2. Discover Sharks, Rays and Sea Turtles

September is also a great time to slow down and discover some of the animals that make SEA LIFE Orlando unique.

The aquarium gives guests the opportunity to see sharks swimming overhead, watch rays glide through the water and meet rescued sea turtles. One of the most memorable residents is Ted, a rescued loggerhead sea turtle featured at the aquarium.

For children, an aquarium visit can be more than a sightseeing stop. It is an opportunity to learn about marine animals, habitats and conservation while seeing the creatures up close.

SEA LIFE Orlando also connects visitors with the broader conservation mission of SEA LIFE, including the work of SEA LIFE Trust to protect marine animals and their habitats.

3. Make the Most of International Drive

International Drive is one of the best areas in Orlando for combining multiple activities in one day.

Known to locals and visitors as I Drive, the area is packed with attractions, restaurants, shops and entertainment. It is also home to ICON Park, making it easy to build an itinerary around SEA LIFE Orlando.

A simple September plan could start with an aquarium visit before heading to another ICON Park attraction, grabbing lunch and continuing your evening on International Drive.

The biggest advantage is convenience. Rather than spending your entire day traveling between different parts of Orlando, you can experience several attractions within the same area.

That makes International Drive particularly useful for families trying to fit as much as possible into an Orlando vacation.

4. Visit ICON Park

If you are searching for things to do in Orlando in September, put ICON Park on your list.

ICON Park brings together attractions, dining and entertainment in one walkable destination on International Drive. A visit to SEA LIFE Orlando can easily become part of a larger day or evening here.

Depending on your itinerary, you can explore the aquarium, enjoy a meal and continue experiencing the attractions around the complex.

It is also a convenient option when you want a break from Orlando's larger theme parks.

For families with younger children, couples looking for a date night or groups wanting to experience several attractions in one location, ICON Park offers plenty of flexibility.

5. Experience Fins & Flights at SEA LIFE Orlando

September brings a completely different way to experience SEA LIFE Orlando with Fins & Flights.

Taking place September 3, 4 and 5, 2026, Fins & Flights is an adults only after hours event at SEA LIFE Orlando. Guests ages 21 and older can explore the aquarium while sampling craft beer from participating Florida breweries.

The event takes place from 7 p.m. to 10 p.m. and includes after hours admission to the aquarium, five craft beer samples and a commemorative tasting glass. Designated driver tickets are also available for guests who want to enjoy the aquarium experience without the beer tastings. 

That makes Fins & Flights a particularly unique option for anyone searching for things to do in Orlando at night in September.

Instead of spending an evening at a traditional bar or beer festival, you can walk beneath sharks, discover marine life and explore the aquarium after regular operating hours.

Fins & Flights at a glance

If you are planning an Orlando trip over Labor Day Weekend, Fins & Flights can be a fun adults only addition to your plans. Tickets and event details are subject to change, so check the official event information before visiting. 

6. Set Sail for Pirates of the Haunted Seas

If you want to add Halloween fun to your September itinerary, keep an eye out for Pirates of the Haunted Seas at SEA LIFE Orlando.

The family friendly event transforms the aquarium into a pirate themed Halloween adventure, bringing together marine life and seasonal entertainment.

For 2026, Pirates of the Haunted Seas is scheduled to return beginning September 19 and continue into November. Guests can encounter Captain Sebastian and explore the aquarium while enjoying the event's pirate themed atmosphere.

The experience builds on the idea that the ocean has plenty of stories of its own. As guests move through SEA LIFE Orlando, they can discover marine animals while becoming part of a pirate adventure.

Captain Sebastian is one of the signature characters associated with the experience. Previous editions have featured pirate meet and greets, stories, scavenger hunt activities and educational elements connected to pirate lore and the ocean.

Because Pirates of the Haunted Seas takes place inside SEA LIFE Orlando, families can combine the seasonal experience with the aquarium's permanent exhibits.

That means your visit is not simply a Halloween event. You can still explore the ocean tunnel, see sharks and rays, meet sea turtles and discover thousands of marine animals.

Why add Pirates of the Haunted Seas to a September trip?

September is when Orlando's Halloween season starts to ramp up, so visiting during the first weeks of the event can be a great way to experience something seasonal while avoiding the traditional October rush.

It is also an easy option for families already planning to visit International Drive.

Tip: Event dates, entertainment and activities can change, so check the official SEA LIFE Orlando event calendar before your visit.

Make a Day Trip to LEGOLAND Florida Resort

If you are looking for family friendly things to do in Orlando in September, consider making the short trip to LEGOLAND® Florida Resort in Winter Haven. The Resort is especially appealing for families with younger children, with more than 50 rides, shows and attractions designed with families in mind.

September also brings several reasons to put LEGOLAND Florida Resort on your fall itinerary, including the return of a classic family coaster, a new indoor coaster and the start of the Resort's Halloween celebration.

Experience Brick or Treat Halloween Fun

Halloween arrives early at LEGOLAND Florida Resort with Brick or Treat, the Resort's family friendly Halloween event taking place on select dates from September 5 through October 31, 2026. The event is included with general park admission on event dates, so families can enjoy Halloween themed entertainment as part of their regular park day.

In 2026, Brick or Treat features an all new trick or treat trail, a glowing Halloween light experience, candy filled cauldrons, exclusive seasonal LEGO® characters and the returning Monster Skytacular drone show.

September event dates include September 5, 6, 12, 19 and 26, making Brick or Treat an easy addition to a fall Orlando vacation.

For families who want Halloween fun without leaving the younger kids behind, LEGOLAND Florida offers a colorful, playful way to celebrate the season.

Ride Coastersaurus When It Reopens

September visitors can also look forward to the return of Coastersaurus, one of LEGOLAND Florida Resort's original roller coasters.

The family wooden coaster takes riders through a prehistoric jungle filled with life sized LEGO brick dinosaurs as the track twists, dips and races through the landscape. Coastersaurus has a minimum rider height of 42 inches.

The attraction is scheduled to reopen August 16, 2026, meaning it should be back in operation for September visitors, giving families another classic LEGOLAND coaster to add to their itinerary.

Its reopening is particularly good news for families looking for kid friendly roller coasters in Florida. Coastersaurus delivers the excitement of a wooden coaster while keeping the experience accessible to younger riders who meet the height requirement.

Blast Off on Galacticoaster

September is also a great time to experience Galacticoaster, LEGOLAND Florida Resort's newest roller coaster and first indoor launch style coaster.

This family friendly attraction takes guests on an immersive space adventure through the LEGO® Galaxy. Before boarding, riders can customize their LEGO spacecraft using interactive touchscreens, choosing elements such as the ship's wings, tail and nose. Then, the adventure launches into a 450-meter galaxy simulation filled with immersive storytelling and high energy thrills.

Galacticoaster has a minimum rider height of 36 inches, with riders under 48 inches required to ride with a supervising companion who is at least 13 years old and 48 inches or taller.

Because the ride is indoors, Galacticoaster is also a useful addition to a September itinerary when Florida heat or afternoon rain makes outdoor activities less appealing.

LEGOLAND Florida September Highlights

Whether your family is looking for Halloween events, kid friendly roller coasters or a new attraction to experience, LEGOLAND Florida Resort gives September visitors several reasons to make the trip from Orlando.

For families staying in Orlando, the LEGOLAND Express Shuttle can also make getting to the Resort easier, with round trip transportation available from ICON Park on International Drive and Disney Springs.

8. Look for Indoor Things to Do in Orlando

One of the best Orlando vacation planning tips for September is to build flexibility into your itinerary.

Florida weather can change quickly, so instead of treating rain as a vacation problem, plan a few indoor activities ahead of time.

Great indoor Orlando activities for September

SEA LIFE Orlando is particularly convenient because it is fully indoors. The aquarium itself describes the experience as a rain or shine attraction, making it an easy addition to a September itinerary. 

10. Plan an Orlando Vacation Around Your Family

The best September itinerary is not necessarily the one with the most attractions. It is the one that gives your family enough flexibility to enjoy the trip.

Consider balancing large theme park days with shorter attraction visits. Plan outdoor activities earlier in the day when possible, and keep indoor attractions available for the hottest or wettest part of the afternoon.

For families staying near International Drive, SEA LIFE Orlando can be an especially convenient addition because it combines education, entertainment and indoor fun in one location.

And with seasonal experiences such as Fins & Flights and Pirates of the Haunted Seas, September offers even more reasons to visit.

Your September Orlando Planning Checklist

Make September Your Month to Explore More of Orlando

There is more to an Orlando vacation than theme parks, and September is a great month to discover it.

You can spend the morning exploring marine life at SEA LIFE Orlando, enjoy lunch at ICON Park, experience another International Drive attraction and finish the evening with dinner nearby.

Families can add Halloween experiences to their itinerary as the season gets underway, while adults can experience Fins & Flights after hours. And with Pirates of the Haunted Seas returning later in September, there is even more seasonal fun to discover beneath the surface.

Whether you are visiting Orlando for a family vacation, planning a Labor Day Weekend getaway or simply looking for something new to do in Central Florida, September offers plenty of opportunities to explore.
