Review for MGM National Harbor Review For MGM National Harbor Google User Mar 17 '17 at 6:41 I really had a great time! No doubts about it. However, the MGM Grand in National Harbor is far from good or great. They really have a lot of "kinks" to work out. They ran out of KahlĂșa in their lobby bar. What??? Also, waiting in line for 15 minutes to get a drink is NOT fun. One final thing, most of the staff was unfamiliar with the casino. Several times I asked them questions on how to find certain machines and they had no clue. They were more interested in their cell phone than helping me. Like I said...I had fun, but these guys look like amateurs. View full site to comment or like
