Gaylord is a beautiful facility. Thankfully, the weather should be nice. Because, it isn't the most convenient location for a BOTL. Hope you'll have a car. You won't be very close to metro and I don't know anything about the buses out there.
If you have a car, you have a few more options. As mentioned, Shelley's is very good and not a difficult trip if you have a car and can find a place to park. Feel free to BYO. Their selection is limited and expensive. However, there is no cutting fee and they don't mind in the least if you bring yours in. Haven't been to Draper's on 14th in a while, but always was a good shop; however hours are quite limited (seem to always be closed at the times that I'm in the area) and I heard you can't smoke in the shop now. I'm not familiar with B&M's right in the area you'll be in, but there are plenty of decent ones in metro area....assuming you have transportation...
