I offered to pick up a friend at Luton Airport, but they have decided they want a go on the Dart. Last time I tried this I parked in front of the Thameslink Parkway station, where the buses used to run from. However, after leaving they had trouble exiting through the Thameslink station (the guard said it's not allowed, but eventually relented). Is there anywhere to park on the Kimpton Road side instead?
