not enough information. is it a paycheck? in-state? personal? none of the above?

casinos cashing unknown checks is akin to extending you gambling credit while it clears. if you don't have history at the Wynn, don't expect them to take unnecessary risk on you.

some of the more corporate, glitzier casinos don't cash checks as policy, particularly paychecks. harrah's claims social responsibility (as if), others just don't want to cater to that demographic. you may try an off-strip "locals" casino instead.

setting up with central credit (in order to cash your own personal checks) takes a few days of bank verification. I don't believe you'll be able to get cleared in time for the weekend though. bring some cash or cash equivalent as a backup, or you may have nothing to gamble with.
