Hi Woody, the second bedroom would be too small for a cot, but there is certainly plenty of room in the living room, which has an open up sofa bed. Two of my kids slept in the second bedroom (each on a queen) and my son took the queen sofa bed in the living room.
You should ask for building 53--it is right next to the main desk and near the main pool, bar and marketplace. We found this very convenient and the rooms are refunrbished. I kept calling in advance and they gave it to me. There are 2 other pools, but this area was the most convenient. You could hear a bit of pool noise at night (before 10)--but we are not early sleepers so it was okay for us. There were lots of activities we never got to because we spent time in the parks. The main desk leaves a message on your phone each day so you should not miss anything. We really enjoyed this place and hope you will too.
