@Steven974 It isn't just a matter of you not coming in close contact with the guests. No one is supposed to be travelling right now for any non-essential reason. In the course of moving around, the guests themselves put other people in danger of infection. Parents having visitation with their children is NOT essential at this time,and these people are flaunting isolation orders, exposing their children to danger, and you would be facilitating this. Stay at home means stay at home. Whoever ignores this is prolonging the spread of infection and the length of time these isolation restrictions will have to remain in place.
First responders are another matter- they do need housing and if you can provide it, that's great.
Are you aware you shouldn't even enter the space to clean and sanitize for at least 3 days after guests leave? If you go in any sooner, you are exposing yourself to risk of infection. Have you read the cleaning advisories for Covid?
