Great experience, though not as colorful as I would have expected. We scuba dived in Abaco and didn't get a chance to explore the Exumas--supposedly the more beautiful islands of the Bahamas.
Overall, the dives were a lot of fun. I love being underwater.
Wear a wet suit! We went in November, and even though it was sunny and warm, we ended up needing wet suits to stay warm during our dives.
