UK holiday booked in a rented house for 10th July with 4 households/8 people. The group is conflicted about whether to cancel given the extension of the rules. If the holiday is cancelled it won't be possible to rearrange.
If you owned a holiday let, would you check or care?
If you lived next door to one, would you report a multi household holiday?
Theoretically, the group could say they are 2 households. Would anyone challenge it?
