Twice in a row this week I've had people instant-book a room and texting me right away, saying they'll arrive after midnight on the first night despite my House Rules clearly requiring a by-10 PM arrival on the first night. I made an exception for the first guest, but today I felt really put upon by these entitled young people and put my foot down. This latest person doesn't even have a proper profile photo, and begs me to cancel so she doesn't lose a night's fee (because I'm on the "Moderate" cancellation program). I answered that I would lose my superhost status if I cancelled HER, and I haven't heard back from her again, but she's still booked. I can't trust Airnb to not penalize me since they are so unfairly pro-guest, and it would take months to sort it out. What should I do, relent and put the key under the mat? In the meantime, I have put my check-in time in all caps on top of my rules, but I think people don't event bother to read them, and it looks unfriendly to me. Any thoughts?
