We are going to do this with our dinner time ADR's, lunch not so much. We'll still be in parks after lunch. Depending what it is, Imight carry something, but I probably won't. I hate to lug extra stuff around.
We only have 2 lunch TS's and 1 breakfast one, so we will still have 4 nights to bring back goodies. I'm excited about that, because some of my party will be eating separate meals at different places and I'd love to taste something from the places they are going to.
