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.
