Just chiming in to encourage you to save a few dollars and grab an inexpensive notebook or a spiral-bound book of index cards (or, if you want a photo autograph book, a small 4x6 or 3x5 flip photo album), along with an oversized pen or large Sharpie (some costumed characters have trouble handling a standard-size pen with their gloves), at home before you leave. We made the mistake of assuming the kids wouldn't be that "into" characters on their first trip, so we packed nothing, and ended up over-paying to buy what was available on-site!
