I completely agree with several of the posts that mention doing research before you go. I know that many people are not Disney "geeks" like most of us on the the boards, but you don't have to completely immerse yourself. I think having your kids watch some Disney movies (both old and new), would be helpful. That way you can see which characters your kids might want to see. I also know that you can get those planning dvds and maps, I think those would be helpful as well. Knowing some of the things each person in the group might want to see and experience before the trip is very helpful.
