Our holiday in Wales is cancelled but then Wales is not opening up on 4 July. So I haven’t had to make a decision.
My daughter runs a holiday let which is perfect for this situation. Totally self contained, in a quiet country area, plenty of walks from the door. Take-aways available from the village pub or small market town four miles away.
Cottage owners have a ream of guidelines to follow to ensure the place is thoroughly clean and disinfected for each booking. Most are leaving at least a day or more between lets, to allow more time. The advice is to wash pillows and duvets between lets, And there is a checklist of items to sanitise, light switches, sockets, even keys, so I don’t think cleanliness should be an issue.
I guess it all depends on the area, and how you like to spend your time. There’s no way I would want to be going anywhere near Bournemouth, for instance!
