Cinnamon Hill is best, Tryall is excellent, Half Moon is good test, White Witch is too hilly, but not bad.
Where you are staying is the most important as the above courses are all OK but spread out (Tryall is furthest).
If you have the time and a driver, Manchester Golf Club is worth the drive to play the oldest course in the Western Hemisphere, 1865 or 1867.
Scotchies Jerk Restaurant has the best Jamaican food, and it's fun. I know people who stayed in villas who went every night, taking their chef with them!
Enjoy Jamaica, just don't be walking drunk at 2 in the morning.
