The Gaylord National Resort Hotel and Convention Center in National Harbor, MD has a spectacular 18-story glass atrium that has sweeping views of the Potomac River. A great spot to see the whole hotel.
Here is a photo of the Gazebo that is inside the Gaylord at the National Harbor. It’s an amazing spot to take wedding, engagement, and special event photos. You have the beautiful background that just pops the Gazebo out and allows you to not have a lot of traffic in the picture.
