Universal's Islands of Adventure is a theme park located in Orlando, Florida. It opened May 28, 1999 as part of an expansion that, along with CityWalk Entertainment District, the Portofino Bay Hotel, and Hard Rock hotel, converted Universal Studios Florida into the Universal Orlando Resort. The park's overall theme is that of a journey of exploration, where guests depart from a main port to visit six islands, each having its own distinct theme, but all emphasizing adventure. On June 18, 2010, the seventh island, The Wizarding World of Harry Potter officially opened at the park, its largest investment since opening. In 2010, Islands of Adventure hosted approximately 5.9 million guests, ranking it #7 among United States parks and #12 worldwide. Like Universal Studios Florida next door, Islands of Adventure has not limited itself to Universal's own library. In fact, with the exception of The Lost Continent and Jurassic Park, the remaining park areas are based on characters licensed from rival studios, many of whom did not own theme parks of their own. Some of these include Seuss Landing, The Wizarding World of Harry Potter, Toon Lagoon and Marvel Super Hero Island.
