Are you staying at WL? If so, you HAVE to do Whispering Canyon!!! Just tell them you want them to go overboard, and they will!
For DH's 35th b-day, they had him and the kids ride stick horses around the restaurant, with the kids singing happy birthday, and he had to sing "Happy birthday to ME!" really loud, or they would make him do it again! It was hysterical! Our waitress was a hoot, and it was alot of fun. Check the dining boards for other WC experiences. Good luck!
