Don't know if this might be an option, but we stayed overnight at the Embassy Suites PHL airport two weeks ago the night before we flew out. It was $109 a night, included free parking for the week and a complimentary shuttle to and from the airport 24/7, plus a complimentary breakfast and cocktail hour in the evening. We are in the Allentown area, and it was less expensive for us to do it this way than to fly out of LVIA. (SEAL wasn't an option for us, their flight schedule stinks!)
