Unsolicited advice,
Take out X amount of dollars that you can afford to lose BEFORE you go to Vegas, then take that amount and buy as much blue chip stock as you can (Proctor and Gamble is low right now and its a steal).
Now go to Vegas, see the sights, rent a machine gun if you want, and watch others gamble.
In 20 years, that money will probably buy you a trip to Australia with plenty left over.
