Location: MGM National Harbor vs The St. Regis Washington, D.C.

MGM National Harbor – Location

  • Waterfront setting with nearby Capital Wheel, Tanger Outlets and National Harbor dining/shops.
  • On-site water taxi access and easy drive to Reagan National Airport.
  • Designed as a resort compound—less walkable into central DC landmarks than a downtown hotel.

Choose MGM if you want a waterfront resort base with easy access to National Harbor attractions and river transport.

The St. Regis Washington, D.C. – Location

The St. Regis is in central Washington, within a few blocks of Lafayette Square, K Street and the White House.

  • Short walks to the White House, Lafayette Square, museums and downtown business addresses.
  • Urban setting with street-level access to DC restaurants, galleries and transit.
  • Addresses guests who want to be in the middle of DC rather than on the waterfront outside the city.

Choose The St. Regis for a central DC location and short walks to key federal and cultural sites.

Rooms: Resort rooms vs Traditional guestrooms

MGM National Harbor – Rooms

MGM offers 308 rooms across 23 floors with a range of resort room types and suites.

  • Room types include Resort Room, Potomac Room, Capital Room and Restore Capital Room (King or two Queens).
  • 308 rooms total with 74 suites and modern in-room amenities; some rooms have Potomac views.
  • Rooms are arranged around resort activity—near restaurants, casino and theater spaces.

MGM’s rooms suit guests who want modern resort accommodations and easy access to on-site entertainment.

The St. Regis Washington, D.C. – Rooms

  • Room types listed include Superior Room, Deluxe, Premier, Grand Room and multiple suites such as the Metropolitan Suite and Caroline Astor Suite.
  • In-room amenities per supplier listing: minibars, DVD players, 32-inch LCD with premium channels, wired and wireless internet.
  • Service offerings include valet, 24-hour front desk and housekeeping on request.

The St. Regis suits travelers who value classic luxury rooms, signature suites and attentive service in a downtown setting.

Dining & drinks: Many venues vs Focused fine dining

MGM National Harbor – Dining & drinks

MGM is a multi-venue resort with casual, midrange and upscale options across 12–15+ dining outlets.

  • Signature options include Voltaggio Brothers Steak House, Ginger (Asian), Osteria Costa (Italian) and Diablo’s Cantina (lively Mexican).
  • Casual options and a food-hall (National Market) make quick meals easy for families or groups.
  • Multiple bars, a sportsbook lounge and late-night options match the casino/resort energy.

MGM is best if you want variety on property—from quick bites to special-occasion steakhouses and nightlife dining.

The St. Regis Washington, D.C. – Dining & drinks

The St. Regis emphasizes traditional fine dining with a single highlighted restaurant and 24-hour room service.

  • The Alhambra is the featured Mediterranean fine-dining restaurant and bar/lounge on property.
  • Continental breakfasts and in-room dining are available for a fee; vegetarian and vegan menu options are listed.
  • Smaller restaurant footprint means more meals off-property in DC’s nearby restaurants and cafés.

The St. Regis fits travelers who prefer an in-hotel fine-dining experience plus easy access to DC’s restaurant scene.

Pools / signature amenity: Rooftop seasonal pool vs Downtown hotel amenities

MGM National Harbor – Pools / signature amenity

MGM’s signature amenity is a seasonal rooftop outdoor pool with river views and cabanas.

  • Pool is seasonal—typically open Memorial Day through Labor Day; hours vary by season.
  • Rooftop location offers Potomac River views and private day pod cabanas with F&B service.
  • Pool is family-friendly and open to children; spa remains adult-only.

MGM delivers a resort-style pool experience for summer stays and families.

The St. Regis Washington, D.C. – Pools / signature amenity

The supplier listing for The St. Regis does not publish an on-site pool.

  • Supplier listing highlights concierge, fitness facilities and bikes to rent.
  • A health or beauty spa is listed as 'nearby' rather than detailed as a full on-site resort spa.
  • Downtown location means city parks and nearby gyms or hotel club facilities may be more relevant than a resort pool.

If a seasonal outdoor pool is a priority, MGM is the clearer choice; The St. Regis does not publish a pool on its supplier listing.

Wellness & nightlife: Large spa and casino nightlife vs Focused luxury service

MGM National Harbor – Wellness & nightlife

MGM pairs a large Clarins-partnered spa with a casino, bars and a theater for nightlife and wellness.

  • The Spa & Salon is 27,000 sq ft with hydrotherapy, Vichy room, 11 treatment rooms and adult-only access to spa spaces.
  • Casino gaming and several bars/lounges provide late-night entertainment; theater hosts concerts and shows.
  • Fitness center access is included via the mandatory resort fee.

MGM combines a substantive wellness facility with active nightlife and live entertainment.

The St. Regis Washington, D.C. – Wellness & nightlife

The St. Regis emphasizes traditional concierge-led luxury and quieter, refined nightlife nearby.

  • Supplier listing notes concierge services, fitness facilities and bicycles to rent.
  • The hotel lists one restaurant and a bar/lounge, with many DC nightlife options a short walk away.
  • Spa is listed as 'nearby' and not described in-depth on the supplier listing; ask the hotel for current on-site spa details if important.

Pick The St. Regis for subdued, polished service and easy access to downtown evening options rather than on-site casino nightlife.
