Review for MGM National Harbor Review For MGM National Harbor Google User Dec 27 '16 at 3:19 Worst casino experience ever. Went on the Monday after Christmas and was overcrowded still. Forget getting food and drinks in under 20min $6 for rail vodka when playing $50 table minimum. Service is slow at best. Slots were not impressive and payout ratio was awful. Lines just to get a soda. Parking is bad. Elevators are insufficient. Decor was bland. Glad I didn't waste 500$ for a room Only good spots were drink girls and pizza was good Will not be going back.
