Depends on three things:
how far south are you willing to go?
how much money do you have to spend?
how important is really good weather to you?
If you can relate to all of the above, I would strongly recommend that you consider Cabo, Mexico.
Excellent golf at Cabo del Sol, Querencia, Palmilla, and you can play ElDorado before the course is modified this next year.
The one thing you can count on without question is that the weather will be perfect. 80's days with light breeze and 60's
at night.
Golf is expensive and crowded during the winter, but there are a lot of people that are looking to do exactly what you are contemplating.
If you go, I hope you have a terrific time. I have on every trip I've taken.
