Universal's Islands of Adventure, commonly known as Islands of Adventure, is a theme park located in Orlando, Florida. It opened May 28, 1999, along with CityWalk as part of an expansion that converted Universal Studios Florida into the Universal Orlando Resort. The slogan for this theme park is "Live the Adventure" (1999–present).
The park's overall theme is that of a journey of exploration, where guests depart from a main port to visit six other distinctly themed islands, all emphasizing adventure. On June 18, 2010, the seventh island, The Wizarding World of Harry Potter (themed to the popular Harry Potter franchise), officially opened at the park, its largest investment since opening. In 2011, Islands of Adventure hosted approximately 7.8 million guests, ranking it sixth among United States parks and tenth 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, Port of Entry, 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 (Dr. Seuss Enterprises), The Wizarding World of Harry Potter (Warner Bros.), Toon Lagoon (Jay Ward Productions and Paramount Pictures) and Marvel Super Hero Island (Marvel Entertainment).
