Great food selection, and they have a beer/wine aisle. Lucky is the mousekeeping cm who gets my room on checkout day as we are forced to leave behind the unopened beer and wine we did not consume
I've found the prices to be average but much better than onsite disney.
We always go to Publix on rt 27 there is one closer on rt 192 but I gas up on the way.I used to go to albertsons but publix was closer and more convienent.The winn-dixie on rt 27 just didnt seem to hAVE as good a selection of fresh fruits and veggies and wasnt impressed with there store at all.
I go to Goodings near the DD area resorts. It is loaded with pre-made stuff, just right for snacks or even a meal if you wish-plenty of salads also. Just do not go near there during the busy hours, tough to get out of the parking lot. There are 2 gas stations on the property.
