Parking at the Mid Stay car park, the walk is only 4 minutes or so but it's uncovered and exposed to the weather, which is not pleasant in the dark winter months. Also, a few times the automatic barrier on entry has not worked (ie it's not read my reg number for a pre booking), so exiting the car park involves calling the office. This shouldn't be a big problem, but the 'call' button on the exit barrier doesn't work properly so I've ended up having to search for the phone number on google and call them. By that time there's a big queue of frustrated cars behind me!
