One benefit of playing at the Landings is that I can move the time slot to my preferred timing in the evening.
Park in the public lot on 18th Street, very close to the Metro. Enter the garage, go as far back as you can, then turn left. Park near the green elevator on your right, take the elevator to the Shops level and you will be directly across from the Landings common area.
Take the blue or yellow to Crystal City. Exit the metro, go up 1 escalator, then take a right into the shops. Take a right at the first intersection and the common area is a short walk on your right, directly across from Hallmark.
