Family vacation to the tropics?

[digital-audiophile]

So I'm starting to put some thought into a winter vacation for the family and since I have never been anywhere tropical I am thinking about maybe Jamaica?

We need a family friendly resort as our daughter will only be just under 2 years old when we go.

Anywhere in the tropics where the wife can get her relaxing time on the beach and I can get in a little snorkling would be awesome.

Any advice or suggestions of the best place for a young family.
