I think this is one reason why Disney has gone to the "price fixe" meal concept-no sharing so we have to spend more money. DH and I used to do the same as you at almost every restaurant. Now we eat almost exclusively counter serve. Plus, on our last trip, for the first time, the other people we were with suggested a grocery delivery service. Besides saving money on Pizza, it was great for the bottled water, lemonade, etc. for our room. One of those things where, after the trip, we said "Why didn't we do this sooner?"
