re: Has anybody done the "Cheers" program on carnival?

I've done it and would do it again in a heartbeat. I never went over my limit, but came close a few days. One of the days I almost went over was actually a port day where I got off the boat.

The main advantage for me was being able to order whatever I wanted without worrying about the price. Hung out in the red frog rum bar and tried a very nice selection of 10+ year old rums.

Even on the light drinking days toward the end, it was nice to order and not have to worry.
