I am a resident of Lewes and so do not visit Rye often. I recently did visit and parked at Jempson’s.
I saw that parking had to be paid for until 4pm so arriving at 2:15 I bought a ticket for two hours. After walking around your beautiful town I made some purchases in Jempson’s and left at 5:15.
I have now received a notice of a parking fine. I think the notice is ambiguous.
No doubt residents of Rye know that there is a limit of two hours parking at all times, but this is not clear to visitors.
