Our group have been coming down to the bvi starting mid 70s. I can speak to our way for meals. We prefer to eat in also. Our group is 8 for two weeks.. WE fill a cooler from home with meats. About 70 pounds including the cooler. The meat at home is much better. We do the major shopping at right way before leaving the dock. All dry goods for the trip. Produce -dairy - bread ect to fill the first 4 days. We fill in the produce dairy along the way at the small stores as this is very hit or miss. This works out fine with some pre planing at home before you leave.
