A note about "taking food down". We always drive and we used to bring down quite a bit of food -- our earliest trips, we would bring everything except the milk and eggs!
THen we scaled back and brought a bit less (buying our meats and such at WDW).
Then we really started price-comparing and realized that we were driving down the road like sardines for 13 hours and saving... nothing!
The prices in Orlando, honestly, aren't that bad, unless you shop at the stores very NEAREST the resorts (Goodings has a higher markup, for example). TH Wal MArt, Super Target, Publix, etc. all have prices comparable to what you see at home. SO I wouldn't have any problem at all shopping from one of these.
That said, we still do our own shopping (using our car), but I think I've had it with THAT! I plan to try Wegoshop on our next trip and leave the shopping to someone else while I sit by the pool, haha!
