Fully understand your concern Linda. I've recently included a very specific request for a copy of potential guests Digital Vaxx Certificates in my Hose Rules . I have always made a point of requesting the email addresses of guests prior to their arrival so I can provide a pdf of specific info that will assist me to personally check them in more easily plus other relevant info. I've found this practice reduces confusion and provides a greater focus on what guests need to know as so many don't bother to fully read listing details. I've not had anyone decline my request for their email address or provide the extra info I've requested.
However while I've been blessed with a succession of excellent guests over the past several months and almost 95% occupancy I've just blocked my calendar for the long term, taking on one only direct long term guest. Reason being simply one of reducing risk posed by potential multiple short term guests. While treble vaxxed I'm a prime candidate for Covid being a fit & healthy senior citizen with an under laying cardiac problem. With the relaxation of borders, quarantine restrictions and rampant escalation of infections here in Queensland , I'm simply not prepared to run the risk, for the immediate future at least. I'll gladly review re activating my listing once the Covid Virus situation improves.
