I've always wanted to do this but which islands are the best?
There are a plethora of Caribbean resorts that offer this luxurious accommodation, including Costa Rica, The Bahamas, Antigua, St. Bart's, Bermuda, St. Lucia and Dominica.
If I wanted a bungalow, I would head straight for the South Pacific. Tahiti or Bora Bora. If you go to less famous islands, you'll get a better deal. Swim-out accommodations are awesome.
