We've made autograph books for several years now but next time I'm going to just scrapbook the pics. Sorry to be a downer, but if you don't have a stroller, they can get heavy! Also I found the character interactions without the autograph books much more spontaeneous and fun- no struggling to find the correct page, dealing with the sharpie, putting the precious book that took hours to make back in it's protective bag only to do it all over again a few minutes later. I had to juggle two and decided by the end of the trip that I would never do it again!
That said, it is nice to go back and look at them and even making them was fun, just not the schlepping in the 90 degree weather!
