You boys are really going to be busy. According to my calculations there are at least 90 casinos in the Las Vegas, North Las Vegas and Henderson areas that have table games. If you only allow 30 minutes for each casino, including travel time, it is going to take 45 hours to visit all of them. Of course the downtown casinos are close enough to walk from one to another. There are 12 casinos downtown that have table games, not counting the Western or the Silver Saddle.
If you have a pocket full of money you might try buying the chips at the cashiers cage. Probably get better chips and will most likely be cheaper in the long run unless you are awfully lucky.
Good luck on your adventure and hope you have transportation for this ventrue.
