Carol, I think this is an excellent idea. Some have discussed doing a nonDisney day before. I wouldn't mind doing something different, maybe even going to a completely different park!

Also, I love the idea of Food and Wine, and might not mind paying a little extra in order to do the extra stuff.
ETA-I don't know how hard it would be to plan, but I would love a day where we go to the Disney Soda Shop, maybe catch something at the El Capitain, and just look around that area. That would be a very fun day to me!
