I would highly suggest a visit to Universal Orlando. It's nothing like Hersheypark, Dorney Park or Six Flags. In fact, it's like Disneyland. Two amazing parks, three amazing hotels, an entertainment district and more. And to top it all off, the parks and hotels are close (walking distance, but a water-taxi is provided), the parks are well maintained and clean, and the employees are extremely friendly and always willing to help make your day even better.
Plus, a lot of the rides at Universal surpass a lot of things Disney has made, such as Revenge of the Mummy, The Amazing Adventures of Spider-Man, Harry Potter and the Forbidden Journey, Men in Black: Alien Attack, etc. And they've got some more intense rides that will help get your adrenaline going such as The Incredible Hulk Coaster, Dragon Challenge and Hollywood Rip, Ride, RockIt.
Sorry, I probably sound like an ad and a broken record, but I think it's worth it to visit Universal Orlando.
