Do we think Instacart would deliver directly to the campsite? That might be worth the premium.
My vote is for the Publix near the outlets primarily because of the quality of foods/service as compared to Winn Dixie. It is also very close.
Yes, go out the arm gate (unmanned) by the overflow parking lot turn left and follow to 535. The traffic is nominal. There are houses and apartments and not much commercial for a while. Then the Publix mall on your left. If you keep going another 10ish minutes till the road dead ends into a mall there is a great pizza place in the mall. And another Publix.
