What type do you use? We went in November 2006 and bought one at Walgreens in Orlando before going into Disney. It's the kind that has a place for the character's signature on one side - and a photo of them on the other. I found that we ran out of pages early on. We have two sons: one is 5 and the other is 8 months. I want to get each of them their own book even though the 8 month old won't know. I don't want to hear about it in the future! I also plan to get retractable sharpies.
