We were there at the end of August. We love CBR.
They are doing a rehab on the main pool, just so you know. Each village has a quiet pool, so it shouldn't be a problem unless you have your heart set on using the main one.
I can't think of any tips other than to try to upgrade to a preferred room if you want to be close to Old Port Royale, or try to get a room in Jamaica or Aruba which is across the little bridge.
We were kind of upgraded for free when we checked in. We got a room in Trinidad North, which is a preferred building, but I'm not sure if all the rooms are preferred so if we weren't upgraded it was as close as you could get without being preferred. We were right across from the bus stop and a pretty short walk away from OPR.
