We are going to Disney World this weekend for the first time with our kids, so we have never really done the character interactions. I am thinking about bring the Junior Encyclopedia of Animated Characters for the characters to sign. My kids are only 2 and 4, so they won't really know what to say to the characters. I, however, would love to ask the characters a couple of interesting questions each. I think the autographs would be a good keepsake, but I worry that they might cut down on the interaction. Is it possible to get good character interaction along with an autograph, or should we just forget the autograph book? Any tips for how to achieve good interaction?
