If you like surfing, there is RincÃ³n at the west side of the island, I've visited The Hornet Dorset and it looks great. I've heard good things about the W Hotel in Vieques.
Places I'd personally avoid: El San Juan is not what it used to be in the past, and El Conquistador is overpriced and overrated although it does have an amazing location.
There is a little of everything, it all depends on your interests. Have fun!
I'm from P.R. and when I visit (almost yearly) I stay with family. So I haven't stayed at many resorts/hotels. But this recommendation above is pretty much spot on.
If you're looking at staying in more of a time-share/apartment style spot, there's some spots in Isabela that are real nice with fair prices. Not much to do around there other than the beach. So really it all depends on what you're looking for.
