We were there in November and it wasn't anywhere near complition. The best that I could get out of anyone as to when it would be ready was, "Soon come mon". We'll be there in April and will report on any progress.
CSS is getting a martini bar? Hadn't heard that but I think it's an awesome idea. Our first trip to Jamaica was to Sandals Whitehouse. They have a martini bar and it was relaxing to hang out there before or after dinner.
CSS martini bar was under construction when we were there just before Thanksgiving. It looked pretty close to being done at that time. Attached is a pic from Nov. 27. It is located on the lower terrace just below the Balloon bar main terrace.
Wish CSS would add a night club...it gets a little lame at night at CSS and the piano bar gets real old after a few days. They really need to mix it up. (they could easily turn the Palazino restaurant into a night club in the evening). I know night life isn't everyone's thing but there are many who do and would enjoy something more than a piano bar later in the evening after the show.
