Over Christmas, Fabian and I went to Puerto Rico for a week. It was a nice escape from the winter and we enjoyed the Caribbean climate a lot. Culebra, a small island to the east of the mainland, is a really nice place with a great beach, probably a lot better in the off season though, but definitely recommendable. Otherwise, it's a bit pricey for what you get, but I guess we are also spoiled from the African wilderness....
