Thanks again, all, for your suggestions! For some reason, Roatan just doesn't thrill me. I know we will go someday but for now I think we will pass - maybe because we were just in Belize, and I guess it's part of the same reef system, even though I'm sure they are different in many ways. And, in trying to decide between the Out islands of the Bahamas, T & C, BVI, and all the other places, there are so many pros and cons for each that it is a really tough decision. But, the main factor is the quality of the diving. And, for that it looks like you can't beat Bonaire. So, thanks oly5050 for saying that we can do some boat dives. Therefore, that's where we are leaning. Boat dives for the first couple of days, until we are truly comfortable, then off we will go in a pick up, tanks in the back, and our copy of Bonaire Shore Diving Made Easy, which I just ordered. I need to make sure the rest of the family is OK with this. But travel times are all similar, ticket prices are, too, and there is the allure of being in a former Dutch colony so we will be able to sample a different culture. We love to dive, but we also love to travel, and see new things, meet people, do cool stuff.
Now, to figure out where to stay, and who to dive with... More decisions!
