I did go with the Dive Shop as Doc suggested. It was fun but would have been better if my friend who was with me could have gone diving as well. We took three dives. My first experience was incredible. I knew from having snorkeled how much there is to see "down there", but I truly had no idea. The water was gorgeous: sea turtles, garden eels, rays, you name it. Beautiful coral of every color. I can't wait to go again. The shop was going to be taking a group to the Stav the next day, but I declined. I decided for myself that that was too advanced a dive for someone with no experience than what she had received the day before! The first dive of the day, once I hopped in the water my BC had a few bubbles coming out of one of the hose connections. I freaked a little but my guide assured me I would be fine. I trusted him, slowed my breathing and did great! The last dive we went down to see some ship wrecks. My arm brushed against one and I got a nasty, itchy rash as a souvenir. No big deal, but I learned that my friend who told me to get a full wet suit told me for a reason. On this trip, I rented everything except the necessities because I wanted to give myself a chance to see what I would like to spend my money on - first on the list, full wet suit! Needless to say, it was a wonderful and surreal experience. Getting certified was one of the best gifts I've given myself.
Oh, and Barbados was nice too! Rather expensive, but lovely. The people made the trip - so generous and hospitable. I would love to go back one of these days. It may not be the best dive destination, but it was a great first trip for me. Thank you all for your advice prior to my going. I felt very confident and that's half the battle for a rookie!
