I recommend these two islands for their nature preserves/forest/jungles/water falls/miles of serene sights:
Guadeloupe <Gwa-duh-loop> - French West Indies and
Tobago (Trinidad & Tobago). Pricey air tickets, car rental and accommodations are to be expected;
Tobago will consume a very long day of travel. While Dominica has its nature preserve and
water falls, I would not be comfortable camping there;
security issues. The best camping
destination would either be Cinnamon Bay or Maho Bay in St. John - USVI. Your
vacation time and
budget are modest for sailboat chartering in the
Caribbean. Read up on St. John - USVI; it will fit your
budget. As for sailing, you can go on one of the
SCUBA diving speed boats, as a snorkeler, for a modest fee.; snorkel around the boat, while the rest are diving. Look-up sunset
sails offered at some of the resorts. They offer a two-hour memorable sailing experience with
steel band
music playing, snacks and
rum punch; it won't break your budget. St. John - USVI is across St. Thomas (Fly to STT
airport, then take a
ferry boat from downtown (Charlotte Amalie <Amma-lia> to St. John.) Have fun! Mauritz
