You'll be fine at the casino at Atlantis. I know the casino's in St Marten you speak off... I wouldn't have played in those either. The Atlantis casino is more like what you expect a casino to be. Although not much different than the one on the ship.

We're just small time gamblers - love the penny and nickle slots because of the bonus rounds. I always take as much as I plan on losing. The ship probably won't miss my $20! They'll have plenty of time to receive my donation on a 9 day cruise!
