This is an old facility, the showers need some work! Had very tight parking spots for our 35 footer. I am not sure I would try this park in a larger rig.
An excellent place to park if you are going to DC. The bus stops at the entrance and tickets are available at office for bus and Metro subway. Site was not the easiest to level on, and noticed lot of the motorhomes had to use blocks under wheels and jacks to level. Excellent place to stop otherwise.
