Premier:  The three most expensive on-site hotels—Portofino Bay Resort, Hard Rock Hotel, and Royal Pacific Resort—are called Premier resorts, and their perks include Universal Express Unlimited, priority restaurant seating, and water taxi transportation to CityWalk.

Preferred: Sapphire Falls Resort is labeled a Preferred resort; it’s a AAA Four Diamond–awarded hotel, just like the Premier properties, and offers water taxi service but lacks free Universal Express or priority restaurant seating.

Prime Value: Cabana Bay Beach Resort and the Aventura Hotel represent the Prime Value resorts. Both have bus and pedestrian access to the attractions (including Volcano Bay), but neither is connected to the water taxi system.

Value: Endless Summer Resort - Dockside Inn and Endless Summer Resort - Surfside Inn and Suites are the first designated as Value hotels, as well as the first located a brief bus ride across I-4 from Universal proper. Regardless of classification, all on-site Universal guests enjoy amenities that surpass any other value-priced hotels in the area.
