*Love* RC San Juan.
Friendly, but not subservient, staff. Great facility. Maybe too close to the airport, but I've never heard any planes from the room. Big ol' casino that sometimes serves free food (grilled ham and cheese) at the tables

.
Best thing is that it's not right next to all the big Condado hotels that might be a little nuts in March for spring break.
Good choice. It's pretty consistent with the other newish RCs (I'm thinking Philly, Battery Park, etc.).
