We've stayed at Caribe every year for past 8/9 years. They have 2 BR, 3BR and some 3BR with a media Room. All the ones we've stayed in with media room had a sleeper sofa in it.
Go to VRBO, you can search by # of BR's on vrbo CARIBE.
Great place: lazy river, 3 outside pools (2 with slides) and 2 indoor pools I think. Got docks on bay and you can fish off 1 of them.
You will have to look at alot of rooms on VRBO to find a deal though.
