Try one of the parking apps (Parking Panda or Spot Hero) if you must drive. Otherwise Metro/Taxi/Uber/lyft are much easier.
Metro there, is easy. Street parking is sparse.
It's best to take the metro. But according to the website, there is a pay lot at the Reeves Center, located at the intersection of 14th and U Sts. It is close to the club, cheap, and your best option. But I would still metro seeing as driving in that part of town is a nightmare.
The streets around had plenty of parking, but if you can - use metro /taxi /uber /lyft. Don't drink and drive.
