I would say for the amount of time you have to wait for Frozen Ever After, it is extremely overrated. You spend the first part of the ride anticipating going to Elsa's castle, just to have her push you away and then it's over in record time. I would say the quality of the AA's would justify about a 20 minute wait for that experience, but an hour and a half to two hours? Just don't get the hype.
I kind of feel similarly about 7dmt, even though it is pictured in my avi.
