Review for MGM National Harbor Review For MGM National Harbor Google User Jan 18 '17 at 3:47 I've had the luxury to get to visit the Casino a few times. I've never gone during the day but at night the Casino has been a real pleasure. I had to wait in line a couple of times but they get you in quick if there is. It's easy to navigate the Casino and your arrival and departure. Parking lot is well marked with easy to read floor and section info so you shouldn't get lost. View full site to comment or like
