Best for a compact, five-star hotel experience in central DC with a noted signature restaurant and an indoor pool.
When MGM National Harbor wins: pick MGM for nightlife, a casino floor, a 3,000-seat theater for concerts/standup, many on-site dining options, big event and wedding capacity, and a large Clarins-linked spa.
When Park Hyatt Washington wins: choose Park Hyatt for a quieter, downtown five-star hotel with a strong culinary draw (Blue Duck Tavern), a year-round indoor pool, and close walkable access to GWU, Embassy Row and the Kennedy Center.
