Not at the moment obviously, but in non covid times.
If someone says they very much want to come and visit, (as in it is their suggestion, not the host's), they earn a good living, (better than the host does), they use hotels when visiting other people and you don't have a spare room, (it would mean someone giving their bed to the guest and sleep in a camp bed)?
Full disclosure; I don't think this is rude at all and wouldn't mind if someone asked me to do it.
