let me preface this by saying we enjoyed CBR overall, however...
We were assigned to Martinique building 26 ground floor parking lot view. We were very disappointed.

Honestly, we felt like we were in an overpriced Holiday Inn. There was no 'magic' looking out the window to a parking lot of cars and the maintainence end of Old Port Royale.
I did go to the Customs House and request a change. We were moved to Martinique Building 25 ground floor (ground floor was necessary due to dh's knee problems) waterview. The difference was drastic.
I would recommend asking for a non-parking lot view, unless you want easy car access. The courtyards and waterviews were beautiful.
