Oh my gosh, sunshine, you almost made my head explode! My two favorite things to do at WDW are the rides and the autograph collecting (with several hugs and pictures applied liberally as needed)! Our modus operandi on each trip is to trek to rides/attractions, but as soon as we see a character meet and greet, everything gets put on hold for those. Then once the characters have all been met or dispersed, back on to whatever attraction we were heading to.
If I could only pick one? Oh geez... I can't do it. This is going to plague me all night!
