    Welcome to Orlando! It has a host of attractions and activities. Ready to join the party and plan a visit to O-Town? Just print out our must-see list.

    Universal Orlando's Islands of Adventure

    The addition of The Wizarding World of Harry Potter is on the list of must-visits for theme park lovers. Each of the park's “islands”—Toon Lagoon, Jurassic Park, Marvel Super Hero Island, Seuss Landing and The Lost Continent—is unique!(407-363-8000)

    Gatorland

    It bills itself as “Orlando's best half-day attraction”, for in a city people are limited by their time and money. Catch Gatorland's animals and handler shows in the afternoon. There's a nighttime run as well. Other fun add-ons include the Gator Night Shine. Gatorland is known as a theme park bargain.(407-855-5496)

    Aquatica

    As one of the city's most unique water parks, Aquatica is a wonderful world of water rides and white sand beaches. And if you enjoy a side of fear with your water-park fun, be sure to check out Ihu's Breakaway Falls. This towering slide is not for the weak heart. The less adventurous will still find plenty of fun playing from one big wave pool to another or flowing down the lazy river through a world of unusual fish. You can also watch dolphins underwater.

    Warbird Adventures

    Warbird Adventures offers you the opportunity to fly like a hero in World War II in the North American Aviation T-6 Texan(also known as the Harvard). Flights last from 15 minutes to an hour. A visit to the nearby Kissimmee Air Museum is a wonderful way to round out the experience. (407-870-7366)
