Enough.

Day 6
Wells-next-the-sea to Beverley

This was the full extent of the facilities at the Wells campsite. After that, and the much-dreaded and every bit as awful as expected drive along the Lincolnshire coast, I booked into a very nice hotel with the dogs for the night.
A word of advice re old vw campervans and the Humber Bridge - go the long way round instead.
