Try the Ramada, they have a park and ride. You may be able to get a crew rate. Its in Essington, if you come up 95 from the south get off the Essington Exit, go to the light turn right its a 1/2mile down n the left. I've just parked and walked up to grab the 1/2 hour shuttle and no one said anything, my car was there when I got home.
