Concierge.com's insider take:

Constructed to rival Disney in 1990, Universal Studios Orlando hasn't quite conquered the Mouse, but it has proven more successful at keeping its attractions fresh and its customers occupied (and cool) while they wait in line with indoor mini-movies and playlets. Although there are technically six themed areas, they fall into two general zones: a pretend backlot where guests are herded into interactive 3-D movies and film-related exhibits, and a lagoon fringed by most of the thrill rides. Among the highlights, Revenge of the Mummy: The Ride is a complex indoor roller coaster in which tombs are plundered, beetles swarm, and fireballs explode with considerable aplomb; in 2008, a long-awaited ride based on "The Simpsons" replaced the dated "Back to the Future" attraction. Young kids should bring their swimsuits for the excellent Curious George–themed children's playground, which is both soaking and addictive.
