Pamela--There are only a few boats that go to blue hole. all the dive shops will book them for you. Talk to Rudy (or anyone) at Bottomtime (bottomtime@btl.net)and he can help you with arrangements. For Lamania trips again they all will book the trips. If you want to talk to the folks who actually go there talk to Searious Adventures (Willy) //www.ambergriscaye.com/searious/index.html or Tashini Tours, (Daniel) (//www.ambergriscaye.com/tanisha/index.html.
The Bluehole is OK (my opinion) It is a deep dive and you should feel comfortable with that fact to really enjoy what the bluehole has to offer. there are some excellent dives on the outter atolls. I think diving around AC is great too.
Plans can change because of weather and be prepared for that and have other plans but don't get disappointed and don't be to programed on your itenary. There is lots to do, including just relaxing. Keep reading the message board (good info) and have a great time. bill
