I was there a couple of years ago. If you simply want to hang out on the beach, it's not a bad place, but entertainment is pretty limited there. The island is very small, and outside of the main town, Oranjestad, there is mostly just desert, with a restaurant and hotel here and there. While I found it relaxing to be there, I wouldn't rate it as high as some of the other islands I have visited. If you want to do some sightseeing, or be somewhere that has a lot of nightspots, I would highly recommend some of the islands located in the Caribbean.
