I met one of the nicest families while waiting in line for Soarin' on our last trip. We got to talking and found out they had family around the area we live! I definitely agree on the friendliness of people at WDW. They must blow out happy air from somewhere to all of WDW to keep people (well, most people) smiling!
I also have to agree on the excitement of being in WDW, although I do enjoy my sleep on vacation as I am not much of a morning person and I get up at 6am every day (which is so early to me

). However, I find myself making bad decisions just to enjoy a little more time in the Disney atmosphere. Like last trip it was cold one day and instead of going back to the room when we came back from DHS and before hopping on a DTD bus, I just hopped on the bus and froze the rest of the night!
