I head to vegas in three weeks. I am staying at a timeshare without a casino. I expect to bring about $3000 with me for 3 days of play - mostly craps - andwill playing in several places - Bellagio, Planet HO. Bills. I will probably be back in vegas once a year on average. Although I do get to Atlantic City quite a bet and play at the Ceasars "total rewards" propoerties down there once a month or so. So my quesiton is this: Should I even bother getting and using cards for the places while I am in Vegas?
