This past March on Celebrity's Millenium on the last night after dinner, I figured I'd use up my last $100 of gambling money at the single-deck blackjack table.
About 4.5 hours later when I left the table, my $100 had turned into $800 and I was able to pay off my cruise tab the next day in cash which felt awesome!
I also came in third place in the black jack tournament earlier in the week, which was nice.
At breakfast in the morning, I ran into my dinner mates who were in the casino with me for awhile and they were shocked I made out so well.
