There is a Walmart on Turkey Lake Road but I do not know if it is a SuperWalmart. There is also a Publix supermarket on Sand Lake Road (in the opposite direction of I Drive). It is on the left hand side about 3/4 mile past Turkey Lake Road.
Thanks everyone!! This is our first trip really staying on-site (booked hotel room for our last trip, but stayed at the rental house near Disney)...whole new experience for us
we used this one in June,,,had everything we needed, short drive to the Royal Pacific which was good as the kids had stuff piled on them, lol....note to self...do NOT rent a hybrid camry...trunk space is lost due to the electric battery!
