Looking at Onestop's website they do list a 1 bedroom suite but it is shown as not available (ever?)

We have stayed at CC a dozen times (last in Feb. 2016), I am not aware of any 1 BR suite unless it is the 1 room across the road that I have known to be used just 1 time that we were there and then only because of an emergency where a couple extended their stay 1 day and had to park it across the street.

I don't see any price listed on CC's website or Onestop's for a 1 BR suite so I'm not sure where you saw a 50% higher price but if you can swing Caymans and Carreras what's the problem lol?
