I stay there almost every time I fly international from Baltimore Internation Airport. The park and fly option is really a ggreat deal. I stay the night before my 6am flight, they transport me, and my luggage, to and from the airport. I can leave my car for up to 14 days, for a dollar a day, with no problems. It may cost an additional $40, when compared to parking at the airport. However, I don't hav to wake up in the early AM, drive, park, and catch the shuttle. The hotel van is about a ten minute ride and it is a door to door service! Heck, they even pack a free breakfast bag you can munch before you catch your flight.
All that to say, I find it a headache free way to start your business trip, or vacation.
This service is available at most hotels near airports though out the United States.
I suggest ya consider this option, especially if you have small children that need all the sleep.before the flight!
