I picked WCC. You can enjoy the boat ride over from the MK, wander around that beautiful WL lobby, go outside and look at the geyser, eat at WCC (enjoying all the antics), then wander outside to the dock and watch the Electrical Water Pageant. Be sure to ask to sit in the main area at WCC requesting a waitress that's really into the antics.
FYI: When we were there Jan 05 the waitress tried to set my 27 y/o son up with a couple of young ladies at a neighboring table. It was hilarious!
