Savannah Bay or Spring Bay, perhaps rent a car rather than get a taxi. No facilities at either though. Speedy’s is right by the ferry dock, although we usually rent from Mahogany. If you make arrangements Puck will meet you at the dock and do the paperwork there. From Savannah, I’d head up to Hog Heaven or Sugarcane restaurant for lunch. Both have great views, and Sugarcane has a pool. I like the food at Sugarcane (as of last March) a bit better but others love Hog Heaven. I think you can get to the beach from Sugarcane as well, just have not done it before.
