Review for MGM National Harbor Review For MGM National Harbor Google User Jan 9 '17 at 18:35 Attractive, upscale. Wide variety of slots, some video poker machines, poker room, gaming tables ($50 min), high stakes room, floor service for drinks, several bars and restaurants from food court to fine dining (we liked the moderately priced TAP Bar). Free parking. Shuttle ($10) to other National Harbor sites. Remember to take ID. No one enters without ID. We saw several people in their 60s and 70s turned away for lack of id. Must be 21.
