guest shows up with extra guests beyond the stated maximim
My insurance rider only allows for 2 guests so that would be a hard no for me.
Another option would be to charge extra for the guests.
Personally, if it’s too much of a crowd, give the guests the option of find a new place for the extra guests and if they won’t budge, then talk to CS and say they are breaking your house rules and want their reservation cancelled per your cancellation policy. NO refunds.
I have in my house rules that showing up with extra guests or guests who are not pre-approved can result in immediate cancellation of the reservation. If you do contact CS, be prepared to answer how you know they have extra and if it’s on camera, but sure you have disclosed them fully.
“Our maximum guest count is clearly stated. Please cancel immediately (or pay x per extra guest, also as clearly stated.”
