I stay at the Sheraton Studio City every trip to Orlando (Usually 1 or more weekend trips per year). I've had nothing but good experiences. The hotel has a movie theme which goes along quite well with a Universal Studios trip. They have free transportation to the parks, as well as a small arcade, restaurant, and fitness club onsite. The hotel was completely renovated a couple years back. Request a room on a higher floor facing Universal if possible. The view is great!
