I have 3 listings in Santa Monica and have been doing this for 3 years and Guest not reading is the most annoying worst part of being a host in my opinion. I actually find it a little odd how little they will read.
When i haven’t heard back from them I message them again and politely ask them to answer the questions i asked so i can release their entry codes…that normally does the trick! LOL.
very very occasionally i have even text them to please go on to Airbnb because i have messaged them and not heard back…But i never communicate anything else outside of the airbnb platform.
Other issue is occasionally some people are not tech savvy enough to be booking online
