For the '84 crowd:
I always tried to play at $5 min. tables, but just to give myself options. i was usually betting 10/15. You can only win what you bet, and if you've got BS and you can afford to lose it, I say give it a shot. BTW: my -250/+500 comment earlier was intended to disuede you from craps, not advocate higher bets on BJ, but whatever; just so you know where I'm coming from.
I think Mike is absolutely right about the variance on craps though. And even after the statistical arguments, Its very easy to bet 10 or 15 after each roll, get 100 onto the table and crap out. I had much more trouble controlling myself with craps.
For a vacation player the best tip I could give is when you're up, cash out and spend some money. We went to the Wynn, dropped $260 of the casinos money on dinner (for 3) and we all felt like rock stars. I'd also recommend Coyote Ugly (at New York, NY) once your good and liqoured up. I wasn't impressed by Hooter's; small, crowded, and bad games, but you might give it a shot (there's always the scenery).
Good Luck, Get Drunk, and Rock out with your Cock out - It's Vegas, Baby!
