In 2003 while staying at the GC we were able to get unlimited fastpasses just for staying onsite. We were there for a week and let me just say it was pure heaven!
I've heard that they have since taken away this perk for onsite guests but it sounds like maybe they still give you a chance to experience this through AAA.
I would overpay just to have the unlimited fastpass.
My cousin who lives about an hour from DL came to visit us one day while we were there. We had ridden everything with fastpasses there before 12 noon. She could not believe it. In all the years she had ever gone to DL she had never ridden that much before noon. (She used our fastpasses)
