OXON HILL, Md. (AP) - Maryland's biggest casino is getting even bigger.
MGM National Harbor opened a $48 million expansion Sunday, less than two years after opening its doors in December 2016.
The Baltimore Sun reports the expansion includes a new, second-floor poker room, off-track horse betting offered in partnership with the Maryland Jockey Club, 285 slot machines and a new terrace overlooking the Potomac River.
Casino officials say the expansion is driven by higher-than-anticipated demand.
