@Suzanne463 "I find it hard to believe that people who stay at Airbnbs would be that deceitful........and if they are, ......well, karma will follow-up"
If guests lie about how many people are staying, lie about being "quiet", when their intention is to throw a party, and lie about their untrained puppy being a service dog, they will lie about being vaccinated. And unfortunately, the "karma" may involve you or others in your household getting sick.
A host on another forum suggested the anti-vaxer, anti-maskers start being referred to as what they really are: Pro- Covid.
My home share has been closed since March 2020, and when I open again, any guest who won't submit their proof of vaccine, or make it quite obvious in their messaging with me that they are adamant about Covid precautions is quite welcome to book elsewhere.
