Three or four days in Vegas, I try not to loose more than 500 bucks or so. I try to set my limit @ 100 bucks a day. If I hit my limit, I go to a movie, I go to the shopping mall, I go sight seeing, etc.
Or I go to the Keno lounge. I can buy 1 buck tickets and the casino supplies me with free booze. LOL - What a deal, how can you go wrong??
