MGM aims to be a destination resort for overnight customers, including international guests. 'I don't think we've felt the results of the economic downturn that other states did.' 'We're still, I think, in a fairly robust economy,' said McDaniel, who teaches sports and entertainment marketing. Maryland casinos have been booming, setting monthly revenue records even before MGM opened. The ballot measure allowed Maryland casinos to offer table games such as blackjack and roulette, and permitted a casino to be built in Prince George's County.
