All sorts of dive spots around the island- big walls, etc. Daily trips are kind of see as you go, many places just take you out and check in the morning, if place #1 is too choppy, or vis is low, they take you somewhere else.
rental gear is decent although you may want to bring a computer to stay under longer, as most do not rent. There's a great videographer if you want some company on your dive...I'm going this weekend, so will see if I can get his name.
Budget has decent rates for rental cars.
the buccaneer has a great restaurant,
the Cruzan Rum factory tour should not be missed (uhhh, free all you can drink after the tour ^ ^
Bring your Designated driver, and it's a bit off the path...
there is a nice glass artist downtown in you are looking for a gift for someone
If you will PM me your address, I'll pick up some activities books at the airport.
