    There are many theme parks in Florida. These amusement parks are designed for kids big and small and have plenty to offer adults, too.

    Magic Kingdom

    Orlando is the center of theme parks in Florida. Of all the parks, no trip to Orlando would be complete without a visit to Magic Kingdom. The center of Disney world, with Main Street USA and Cinderella's Castle, is here at Magic Kingdom. There are rides for kids of all ages as well as shopping and dining.

    Epcot

    After Magic Kingdom, the best-known theme park in Disney World is Epcot. This is a good place for curious kids who want to learn about the planets, the stars, and the workings of the human body. The good and wine festival is another big draw to Epcot.

    Animal kingdom

    When it comes to the top 4 Florida theme parks, Animal kingdom must be on the list. You may have had the chance to go to a zoo before, but Animal kingdom brings the concept of a zoo to new heights. Sure you can go on the safari (狩猎旅行), but there are also rides on different animals, even dinosaurs.

    Universal's Island of Adventure

    If your kids have the need for speed, you will surely want to check out Universal's Island of Adventure. Here roller coasters and thrill rides will combine the magic of the movies with plenty of twists (旋转) and turns. You'll also find Wizarding World of Harry Potter here---something the whole family is sure to enjoy.
