Plus, the property's $23.58 daily resort fee covers high-speed internet access. All feature neutral color schemes and come equipped with LCD televisions, Serta pillow-top mattresses and minibars. When it's time to retire for the evening, the resort has 308 guest rooms and suites to choose from.

Other available facilities include a 27,000-square-foot spa and several bars and lounges. Located in Oxon Hill, MGM National Harbor is 1.1 km from downtown National Harbor and 7.5 km from Old Town Alexandria. Travelers can catch a live performance in the 3,000-seat theater, admire the conservatory's themed floral arrangements or go for a dip in the outdoor swimming pool. But MGM National Harbor offers more than just top-notch eateries. Although several reviewers said this pricey MGM Resorts outpost – which sits 11 miles south of Washington, D.C., in Oxon Hill, Maryland – pales in comparison to Las Vegas' casinos, many appreciated its close proximity to the National Harbor entertainment complex, as well as its variety of shops and restaurants. Dining options range from a Shake Shack to an upscale food court to celebrity chef-affiliated locales like the Voltaggio Brothers Steak House.
