The outer car park for shorter stays is really cramped and difficult to park in as it's on a hill. Even more awkward to get out again! I often end up going to the inner car park as it's easier and I can pay by mobile although the only price is for 12 hours. Also unsavoury types hang about the outer car park trying to get you to buy/sell used tickets. The inner car park prints your reg plate on the ticket which stops this although is annoying to type out on the machine.
