I do not have an annual pass right now, but plan on getting one when I arrive in Disney World. Am I able to book a room with an AP discount without an AP in my hand? My plan is to check in to my hotel, then go to a park and upgrade my park hopper to an annual pass, then when I return to the hotel later I would present my AP. Is this even an option? I think I have heard Disney will give you 24 hours after check in to show your AP, or you would end up paying full price for the room. I did a quick search and couldn't find what I am looking for, but I think others have posted about this.
