To big time gamblers like Las Vegas resorts do for their big rollers? I would think a, say, $800 ticket in exchange for a big roller's expected loss in the casino would be worth the risk. After all, wouldn't they want to do that for cabins that go unsold anyway?
Book me on your next cruise and enjoy your personal punching bag.
There are several companies around who do just that. They have a number of cruises each year on various ships, where table limits are raised and high rollers are given complimentary passage.
There's also several poker cruises, for the ever growing Texas Hold Em crowd.
