My wife was also a newbie on our first Bahama trip to Green Turtle, but I gave her the "full immersion" into the culture right away, even though she couldn't swim! Did manage to get her doing some snorkeling before we left, however. Although she and our daughter flew over while I ran the boat over with a buddy of mine, they LOVED the place and the friendliness of the natives! They became quite friendly with the folks in Lowes grocery, but said they were very conservative (this was back in the 70's); the locals were clearly offended and just barely polite to some gals that came in off a sailboat wearing string bikinis!

Green Turtle is about 60% white and a bit less conservative than Man O'War, which is ~100% white, has numerous churches, and no bars or liquor stores, but go easy on the rum raisin ice cream at the Dock 'n Dine restaurant . . . that stuff will give you a hangover!
