Long-term parking is available at the University of Maryland during our conference. You receive it on a first-come, first-served basis. There should be plenty.
At UMD, you rent a spot in the garage for hours, a day, or multi-days (at about $20/day). Park in the garage and then pay for the space at the kiosk in the garage (the parking fees are not included in the conference registration). Since transportation is taken care of with your conference fee, you can park your car in the lot and leave it for the entirety of the conference.
The best parking for us is Mowatt Lane Garage (Sector D12, Building #404).
