An update to an old thread, as I've parked several times in the last few weeks:

SunPark on Scott Way, hugely expensive, $32 for 18 hours, but lots of room (wide spaces), quick to pickup, and very, very close to terminals. You pay more for convenience.

Pacifico Airport Valet: Used them twice in the last few months. I don't like them for some reason that is hard to figure out. Even though the company says no tipping, the drivers make it known you still can. When you walk in the office to drop your car it seems seedy, and smells like people smoke, so you wonder if they do that in your car. And they can't wash you car anymore. And they always seem rushed, too.

Ramada: The old standby. Big lot, no frills, long(er) drive to get dropped off, and picked up. After a long trip, and you're eager to get back to your car, it's annoying that they always drop people off at the hotel entrance first, and then deliver you to the parking lot. They're trying to be both a close-to-the-airport hotel with van service, and a big airport parking lot. And the wait times to get picked up can be up fifteen minutes.

PHL Economy Lot: Anybody with recent experience care to update us?
