Coral Bay Villas is a great place, the Penlands who developed and now manage the condos (they also live there) are wonderful people. CBV is small (only 6 units I beleive) and peaceful.
They also developed and manage Belizan Shores which has a great pool which I'm sure you could go up and enjoy. I'm sure your going to have a wonderful time.
