If the game Monopoly taught us anything, it's that owning a car is a responsibility equal to that of owning a dog (or a thimble) and that free parking is something that happens to other people. Advance to airport parking with today's Groupon: for $10, you get up to seven days of airport parking with free shuttle service from Dulles Park Fly at Fairfield Inn & Suites Dulles Airport in Sterling (a $70 value).

Stationed only a few minutes' drive outside the Washington/Dulles International Airport, Dulles Park Fly offers cars a safe port of rest while their owners traverse the friendly skies. Globetrotting travelers and business trekkers need only drop off their car at the Fairfield Inn & Suites, where it's free to crash for up to seven days. From the lobby, customers can call to arrange for a lift while enjoying a complimentary cup of coffee or printing their boarding pass. Friendly attendants help with luggage and get commuters on their way with a five-minute rocketless shuttle ride. By taking the back way into the airport, delays are avoided and riders can count on being on time for their frisking and flight. After returning and retrieving their luggage, journeyers simply call Dulles Park Fly and the shuttle will appear at loading area 2H to reunite them with their excited, tailpipe-wagging car.
