Well, I don't know if it will be worth it or not, but I took the plunge & did the same when I made our reservation for June. Can't wait to find out.
One thing for sure - it will make our suitcases a lot lighter, not having to pack food for breakfast, snacks, & bottled H2O. On our last trip to WDW, I had filled our suitcases with these sorts of things. Trying to not have quite so many suitcases, I packed our 2 biggest ones (there were 4 of us traveling). When we got to the airport & checked our bags I ended up having to take out a bunch of the bottled waters & put them in our carry on's because our checked bags were over the weight limit!!!!
