Free parking here - but there are about twice as many cars as parking places.... the access roads and the main road next to the site get parked up. We're on an industrial estate in the middle of nowhere (in Livingston, central Scotland). There's a couple of bike racks (which I have never seen totally filled up), we have showers and some lockers. The company (together with the company in the next building) also runs a minibus at morning and evening commute times to the nearest railway station as public transport from there is pretty poor - the minibus gets quite well used I think.
