I have a confirmed reservation that began on May 3rd for one guest. She is now asking about adding two additional guests. The home can accommodate the additional guests and I am fine with it but had a couple questions: (1) what’s a reasonable additional fee/ is there a way to find out what the smart pricing fee would have been for 2 guests and (2) the original guest is Airbnb “approved” is there a way to add guest info in Airbnb (id be more comfortable knowing who the additional guests were) if not does my host insurance remain the same?
