What to pack for a stay at MGM National Harbor

Pack ID, a credit card for the required incidental authorization or refundable deposit, smart-casual clothes for dining, swimwear for the seasonal rooftop pool, and workout gear if you plan to use the fitness center or spa. Don’t bring pets (service animals only); the resort fee and deposit cover certain in-room amenities and fitness access.
