We are taking our two girls (ages 4 and 2) for their first trip at the end of February so naturally I'm planning on getting them things this Christmas that can be used on the trip. I was going to get them autograph books but my husband thought they would just get thrown in the closet once we got home and not really used. So I'm wondering if any of you veterans have any suggestions on other items that have worked well for autographs that can be used after the trip. Bonus points if you have links to where I can find them. Thanks for your help!
