My grandson is getting married in June, 2006, and our gift to them will be their honeymoon. They want to go to a "beach" and be able to sun bathe, and see the beautiful water. I have heard St. Martins was a wonderful place, but am concerned about a 23-21 year old couple who haven't done much traveling alone. Any thoughts, suggestions, other ideas. I have over a year to plan this, but I want it to be as nice as possible.
