you may or may not want to "pre book" dives. Daily diving in AC is not guaranteed. There are often times the ocean conditions don't allow boats to go out beyond the reef. I have never had a problem paying daily for diving. If conditions don't permit,or for some reason I can't or don't want to dive I am not financially obligated. Amigos is good for blue hole. also check out Bottom Time, they are excellent for local dives and very reasonable in their prices.
