We are staying at Cabana bay...two adults and two teens. The teens have 2 day PTP tix with 3rd day free from UT. Adults have 1 day PTP tix. I plan to upgrade 1 of the tickets to a Power Pass for the aph discount on our room. Can I upgrade one of the teen's tickets and use it for the discount or must it be my ticket because the room is reserved in my name?
