It is a very small casino and is located in the Greathouse. There are slots and video machines plus an automated roulette wheel. When we were there in January, we stayed in the GH and usually saw a couple people in there every night. It is not Vegas or even Aruba style action. Bob certainly enjoyed spending a few minutes in there most evenings.
Yes, the Casino @ CSA does exist. It is a small room with a few slots and video type games.
Don't expect a big time casino like some of the other islands have
Yep...this ain't Vegas. I can tell you though that another couple we traveled with visited several times and won a fair amount at the slots. It's a fun way to pass a little time in the evening if you enjoy that kind of thing.
