It really depends on what you want to be closer to.
We were in Casitas 2 and we loved it!!! We had a standard view room, and it looked out over a beautiful courtyard. It was a short walk to El Centro, the bus stop, the laundry room and the exercise room, but quite a hike to the Dig Site. There was a quiet pool next to our building, but my kids and quiet don't go together at all!!
I think that the Cabanas are closer to the Dig Site pool, but further from El Centro.
