How funny you are going to be more spontaneous on this trip when now it's all about scheduling your rides in advance too.
I stayed at WL for the first time for a couple of nights last November and loved it there. I saw something really neat one evening, a couple had a bottle of wine and it looked like they had ordered some bread and a cheese flight and another appetizer from Artist's Point and were sitting in the lobby dining....I am doing that next time I stay at WL.
I also rode the boat to the Campsites and did the Chip n Dale thing with the smores and movie one evening with the kiddos and that was really a lot of fun for them...
Enjoy your visit, I think WL was a great pick!
I'm all for scheduling fast pass. But with meals it has often felt like a hassle to have to plan the whole day around where you are having dinner.
