U.S. Virgin Islands
We stayed at Cinnamon Bay while on St. John. A bare site was under $30.00 that year and no tax is charged on bare sites. Five days cost us under $150. You can easily spend that much for one night in a hotel or villa.
The bare sites are basically walk-in site but the park provides aluminum carts for transporting your gear. On our first trip we had two 50# duffle bags. The cart was a most welcomed. Next trip we'll be scaling back a bit. After all, this is the Caribbean, how much stuff do you really need?
Our basic gear consists of a 4 season backpack tent, sleeping bag, camp stove (propane for the Virgin Islands), freeze dried food, snorkel, mask and fins, and clothing for the duration. One thing to keep in mind is that you are probably not going to need more than a swimsuit and a few pair of shorts and shirts. We packed a good shirt and a good pair of pants to wear to dinner on a couple of nights and the rest was just excess baggage.
