Island Star do this, so presumably Island Escape does as well.
Good game isn't it.
Most ships play stud poker, but there are usually variations on the American ships (Caribbean stud).
One thing to be very careful of though, is that more and more ship Casino operators DO NOT allow the Croupiers to keep their tips. Celebration is one of them (we were on her 2nd - 9th of October).
I don't think it's right, as the Operators make enough out of us already. Always find out at the start of your cruise, then slip them a few bob on the quiet on the last night.
Yes, Island Escape and Island Star have a bigger casino than the Thomson cruises and have stud po.ker.
