I do not want to wait until they arrive... and these are other issues beyind pets.
People who eat in their room, people whose SUV won't fit in my parking spot (despite a clear warning that parking is only available for small/medium cars). No guests over or entertaining.. etc.
Once they are here - and staying with you - you can't do anything about those things, because they can then give you a rating and if you do anything negative, they will rate you poorly and you lose superhost.
These are things they don't read when they instant book. If they send an inquiry - I can ask them about these things... and weed them out in advance.
Even with instant book, I do have this conversation, but some people wait a week or more to respond - so in that time, my home is booked and I could be losing bookings from others. So it's not right that they can book my home and then cancel a week or 2 later without any repurcussions - all because they didn't bother to read the listing, or my message at the time of booking.
