When neglected for long periods of time, cars may act out by sleeping in the street and consorting with tractors. Keep your car safely attended while you’re away with today's Groupon: for $20, you get up to 14 days of airport parking from Dulles Park Fly, located at Fairfield Inn & Suites Dulles Airport in Sterling (up to a $140 value).

Situated about a mile from Dulles International Airport, Dulles Park Fly's lot safely houses ground-transport vessels as owners venture into the skies. Patrons can drop their vehicles off and take advantage of a free shuttle service, which provides a five-minute ride to the airport with luggage assistance and rousing group sing-alongs en route. Shuttles run from 4:30 a.m. to midnight. Upon returning from a trip of up to 14 days, customers can summon a shuttle van to loading area 2H with a quick phone call, then be swiftly transported back to the lot and the warm embrace of four-wheeled rides. Travelers may visit Dulles Park Fly's lobby for a complimentary cup of coffee and to print out a copy of their boarding pass or a diagram of their airplane’s ticklish spots.
