We have done two weekends in Port A this summer. Here are some pointers.
1. Rent one of the golf carts. Makes getting stuff to and from the beach easy.
2. Venetian Hot Plate, Marcel's- good food, a little pricey, Port A pizzeria, great pizza.
3. Black Horse Saloon- awesome burgers- Their big burger- 1lb meat, onion rings, fried jalepenos, BBQ sauce, cheese, grilled onions, bacon, etc... AMAZING!
4. Any restaurant on the water is tourist food. Just grab a drink, enjoy the view.
5. Relax, have fun. Lots of sunscreen ( buy at the local Stripes- cheaper than the beach stores).
