We are heading to Couple Negril in 30 days. Looking forward to it as the winter has been nasty here already and we definitely need and deserve a break.

The questions are simply:

1) diving. I am planning on brining my own fins, boots, snorkle and mask. Any recommendations? Going to do a 30 ft ish dive first (want to see how the ears adjust to the flight) and then a deep water.
2) Not worried about clothing. Been south before and have learned that overpacking is not the way to go. But... What is the one thing that is NEEDED?
3) The Appletons Rum tour. Anyone do it, is it worth it? I think I am drawn to the personalize bottle.....
4) best drink to have?

Going to be there Jan 19 to the 26th.
