the closest place for food,coke and beers is hess garages on site.there is one near the broardwalk.And one near to downtown disney.
For the Downtown disney one no nead for taxi catch a bus to downtown disney get of at second stop where planet holywood and new dinaosor resturant,its a 3 min walk to hess garage over the road.
We usaly take a rooler sports bag to hold beers(looks strange getting on bus with case of beers in hand

)Would get cokes and water there as well.Plus a few krespie kream dounuts
Then back on bus to resort
Cost equvilant to supermarkets offsite
Saves paying disney prices for beers
