Universal's Islans of Adventure is a theme park located in Orlando, Florida. It opened in May 1999 as part of an expansion that, along with CityWalk and the Portofino Bay and Hard Rock hotels, 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 on an "inland sea" to visit five "islands," each having its own distinct theme, but all emphasizing fun and adventure. A planned sixth island, to open in late 2009, will be based on the popular Harry Potter franchise.
