@Anonymous I haven't had any extra drama. I accept 100% of bookings, so if I cut that to 67% I would have excluded a lot of great guest for no reason at all. Like I said everyone is different, and reducing occupancy is not my objective now.
The topic was guest with no reviews, so I mentioned the three I just happened to deal with over 24 hours. I think they were a good example of some the issues with new guest.
Of course I would never ask any guest if they could change their reservation to accommodate another guest. Its just a typical challenging situation for host to educate new guest, which is the topic of the conversation.
I often get inquiries that turn into great guest. I included that example because if a host uses Instant Book but changed the settings for guest to have reviews to IB, host is essentially requiring an inquiry to accompany a reservation request. That guest would have been a good example of requiring new guest with no reviews to inquire first.
But for my listing now screening guest and asking questions would create more problems that my existing approach for my particular listing. That could change, though, as some of us are contemplating changes.
I could also start screening all guest, as you suggested, but so far it isn't necessary, but do appreciate you mentioning your experience with it.
I commented here to provide my perspective and was clear that I understand and respect that each listing and host is different.
If hosting doesn't work out there is always support ambassador.
