The Caribe does service conventions, but there are 3 towers and families are put in a separate tower than convention goers. After staying at the Caribe 3 times, we booked the HIFS when it was brand new. We checked in, saw the room, the pool, the restaurant, and immediately checked out and went straight to the Caribe. The HIFS has exterior entry doors for the rooms, and the Caribe has interior room entrances. The difference in quality was huge to us. I know there are lots of HIFS fans out there, but if the $$ difference isn't much I would choose the Caribe in a heartbeat. It has a great pool w/slide as well.
