Yes it is possible to do that in almost every casino, but you have to have Bank Quality Dumps+Full Infos+IDs. I'm not sure if many people do it these days since cash advance fraud security has been upgraded from spring '09 in most casinos.
I wouldn't advise it. A casino is like a stronghold and you are ultimately fucked if you get caught. There were a couple of articles on people being caught in vegas on carding and atm skimmers. Your better off befriending some shop owners and just cashing out through their merchant account
True my friend, Casinos are very dangerous to cashout, stay away from casinos from any place in the world, if a card you swipe in casino says referral, belive me, they will call and you get busted my friend, try another things
