We stayed in the pyramid. It is a novelty thing. The slanted windows make the rooms a bit different. The windows are black and absorb heat. The AC works very hard. The AC will be constantly running. Our friends had the honeymoon suite. Even with two AC units, the room was barely cool. I would suggest the towers.
The pool is nice. We used one of the cabanas for a more private pool. ALL of the pools are only 3 feet deep. You will be walking around on your knees all day.
The location of the hotel is great but the shallow pool is a deal breaker.
