Will be traveling to Bahamas for the first time next May. We have a group of 11 adults and will be renting a house. The best rentals in our price range are on Eleuthera, which looks beautiful and amazing to me! However, I keep reading the water in Exuma can't be beat. Is the water in Exuma REALLY that much better (bluer, calmer) than Eleuthera? Enough to push the budget over to stay on Exuma? Thanks!!
