I was at Michaels yesterday and they had these little plastic Mickey and Pooh photo albums which hold 24 pictures. They were only $1. I got them for my DS for autograph books this year. I can put a 3 x 5 card in one side to get signed and take a pic of them with the character for the other side. It'll be a great CHEAP souvenir for them to keep and play with after the trip.
