I don't like the idea because unlike rides the characters are not constantly there. They have breaks in between. The way this was described to me broke my heart. A woman was standing in line with her very young daughter waiting to see buzz and woody. They were handing out fastpasses at a table around the corner, so most people were unaware of they were giving them out including the mother. So they wait there turn and just as they were about to meet buzz and woody a group comes up with their fastpasses and are told to go next. Now to a little girl this looks like butting in line. Even worse, when it was her turn it was time for their break so buzz and woody left and they had to wait even longer. This is really difficult to explain to very young children who are extremely excited to meet Mickey or who ever. On the rides it is ok because fastpass looks just like another line and the ride doesn't take a break. I could imagine getting stuck in the non-fastpass lane of a meet and great forever. Now if they want to give everyone an alotted time, kind of like manditory fastpass, I think that might work. But I think regular fastpass would make for a lot of upset little kids. JMHO. Being the mom of a 2 1/2 ds, I could see it as a problem.
