Universal Express Pass is not a virtual queuing service, where users receive a specific time to return to the priority line.
Instead, guests who have purchased (or otherwise received) the pass may enter the "Universal Express" line for a considerably shortened queueing time.
The cost of the pass varies based on what parks are selected and even what day is selected, with higher prices charged on peak operating days during the year.
[1] [2] [3] Guests at three of Universal Orlando's on-site resorts — the Hard Rock Hotel, the Royal Pacific Resort, and the Portofino Bay Hotel — get complimentary unlimited use of the faster lines during their stay.
Guests who hold Universal Orlando's Premier Annual Pass can use it once per day on every participating ride after 4 pm.
