I sailed on the Costa Atlantica in Jan 02, and the casino was only open the first day maybe 10 min. when I hit a jackpot of $1,080.00 on the dollar machine. The pot would have been larger but I only had one coin in instead of 3. The next day I hit another jackpot on the same machine, and one more large jackpot before the week was over. Hit close to 4K on the 3 machines. One never knows when a machine will pay out, and this is why it is called gambling!
