Big pens are good, and, just as important, pens that don't leak. Sharpie markers are also supose to be good, but they can be dangerous as well since it's very easy for a shapie mark to ruin Mickey's white gloves.
WDW just happen to do thick pens,by chance they are right next to the autograph books!Some of the characters have stamps as their hands don't "work".If your kids are small always get them to approach from the front as some of the characters peripheral vision isn't great.Have the book open at the page as this saves time,more so for the people waiting,also have your camera ready to go as some people can be a bit impatient & before you know it your photo is ruined by someone walking across it!!
Hope this helps SD
