If you book a package through AAA you will receive a voucher for the members of your party to attend a story time at MK. The stories are on select days of the week (I think Monday and Thursday) at 3 times in the late afternoon. I think we are scheduled at 5:10 PM. A character comes out (they don't know which character, so they can't tell you ahead of time) and reads a story, then you can take photos with the character. Seating is limited and can be booked 90 days out. The times are about 40 minutes apart but the story experience is only supposed to be about 20 minutes. I have heard mixed reports about whether there are any sort of snacks or drinks offered. The AAA lounge in Tomorrowland is closed, and the story is done at Exposition Hall.
We have 4 adults and an almost-10-year-old but we are going to go check it out just so we can say we went. It IS part of the package, so we might as well see for ourselves.
