a friend of mine who recently went to exuma has said that thats probably the bluest water u will ever find in the world. She also was went to Atlantis but said it was as crazy good as ppl say. I kinda looked at it for her and helped her with a game plan with Atlantis, we found that the comfort inn is probably a good deal to do instead of Marriott. for her, it was like $220 for 2 night, includes atlantis access, breakfast. I also found out that Atlantis owners are having a dispute with Baha Mar so they only allow certain hotel guest in. I think i good idea would be to hit Atlantis with comfort inn, then move over to Baha Mar using Hyatt points.
I think the next watery destination for me is Exuma. Hawaii was originally on my list, but that no longer in the plan. I may still try it on my own though.
