Best for entertainment, nightlife, large groups and varied dining across many on-site venues.

Best for a quieter, boutique luxury stay close to Georgetown with individually decorated rooms and a small number of high-touch services.
When MGM National Harbor wins: choose MGM if you want casino gaming, large-scale entertainment (a 3,000-seat theater), many restaurants and bars, big meeting/wedding spaces, and a seasonal rooftop pool with river views.
When Rosewood Washington, D.C. wins: choose Rosewood for a smaller, quieter five-star stay in Georgetown with individually decorated guestrooms, a focused restaurant/bar program (CUT D.C. and two lounges), more residential scale and concierge-driven service.
Bottom line: both are five-star properties aimed at luxury travelers, but they serve different needs — MGM is a full-scale casino resort and event campus; Rosewood is a boutique luxury hotel better suited to travelers seeking a compact, high-service Georgetown base.
