globalairportparking.com pick a hotel from the listing and book. it is prepaid. then call in one day before at the hotel directly to arrange your shuttle-- shuttles run roughly every forty minutes or so and depends on location- one shuttle may serve a few hotels so allow extra time- the savings are only worthwhile if you park for three days or more-- otherwise go to remote parking on DFW. I usually pick Sleep Inn DFW North b/c on the way back from my trip they usually drop off here first.
