On break from military training in Gila Bend, Ariz., Harry has traveled throughout the western portion of the country, including three nights in Las Vegas recently.
Harry arrived in Los Angeles Tuesday evening and visited Universal Studios Wednesday, People magazine reported.
He took a behind-the-scenes tour of the studio before hitting up various rides including King Kong 360 3-D, the War of the Worlds, Jurassic Park: The Ride, and Revenge of the Mummy.
A win at a carnival game netted the prince a giant stuffed Curious George, which he gave to a nearby child.
Harry was seen later that night at his Beverly Hills hotel spending time with friends, a source told People.
