Hopefully just a ship-by-ship thing...I won't play near as much with $15 minimums...
Some months ago folks reported $10 minimums on their cruises but there were still $6 minimum tables on my Sunshine cruise around the same time. Maybe Carnival is trying to test these things on a ship-by-ship basis. I know just before the shutdown, the Sunshine's roulette table had a 000 position but tha went away during the restart.
All these price hikes and cuts in quality, Carnival is really challenging the notion of cruising being the best value vacation.
