If you don't rent a car, taking the train is the least expensive option. Using a shuttle or car service ranges from $125 to $200 one way for 3 people with 3 carry on bags and 1 travel wheel chair. About 3 weeks ago, I contacted the companies listed on Philadelphia's airport website and the shuttle service recommended by Caesars AC. In AC, you can take the Jitney from your hotel to the train station, the AC train to the 30th Street Station, then the Septa train to the airport.
