I would like to see Airbnb have a clear option for guest reservation that states no extra guests allowed when desired by host . In the extra guest fee option under extra fees would be perfect. I was severely impacted by a guest covertly bringing in extra people when my listing stated 2 guests only in several places. (The well and septic are approved for 2 adult capacity) This caused the well pump to break, and resulted in septic repairs ($2000), loss of revenue reimbursing current guest, cancelling future guests so work could be accomplished. I understand host cancellations affect super host status, too! I believe clear communication is the key. Help me encourage Airbnb to clarify this for guests and hosts. Please add no extra guests option where applicable. Thanks!
