Yes!!! I needed to book a few days after my cruise and nothing at the values was open for a standard AAA room. I could only get preferred at Sports and I really didn't want to stay there. I checked back a few weeks later and had my choice of all 4 valueresorts and booked Music. Same thing happened with my precruise dates..they could only offer me Pop and Movies for AAA when I originally called. I had called just to get the price at that time. When I called back, they had Pop, Movies, or preferred at Music. I took Pop since I've never stayed there before. So yes, availability for AAA rates does change.
