We are visiting elderly in-laws (overnight stay) with our two children. In laws went camping last week (unknown to me). They said the campsite was busy, facilities were cleaned regularly. Campsite is in the north of England. Personally, I would not go to a busy campsite at this time - and I’m now wondering if I should not see my mum (elderly) until I’m sure they/my family haven’t been exposed to anything. I went on a walk yesterday and in laws are not great at socially distancing - were talking to people on the walk and getting too close (I could see people backing off).
