The Gaylord is classy and impressive. It's an easy walk to attractions at National Harbor. Also, the DC Circulator shuttle takes you to Tanger Outlets and MGM Casino. The biggest challenge for us, during New Year's weekend, was finding affordable food. Reservations were very difficult to come by, both inside and outside the Gaylord. The hotel's marketplace is well stocked but quite expensive.
Anyway, the Gaylord is a beautiful destination. An added bonus was the courtesy of the staff. I enjoyed chatting with the concierge Anthony and I was pleased how housekeeping anticipated our needs.
