DH and I have 5 days in March. I want beach, drinks, sleeping in, very little activity. Luxury, without being over-the-top. Direct flight from BWI or DCA is the best, but layover is OK as long as we don't waste an entire day traveling. We'd like a no-kids resort and we prefer smaller, intimate places to giant mega-resorts. We do not want to go to Jamaica, Puerto Rico or Aruba. Where would you go?
