I live in Florida (in the winter). It is pretty dull except if you like sand (beaches). I have lived in California for 4 years. That is a truely exciting state. Regardless where you go (except LA) it is world class. Puerto Rico I don't know. I only hear that there is a lot of crime.
The cruise suggestion is good too. There are a lot now out of Florida and if you shop around, they are not very expensive. On a cost/day basis they are actually pretty cheap.
Edit: Hibernation is a different story. For that Florida is the best because of the low prices in most areas. And the sun shines all winter.
