Wightgal, every situation is different. I make the decision on who is in the house, what time it is etc. I have had to find alternative accommodation for some guests on occasion.
We have a no child policy because of stairs and balconies, but still have groups turn up with children. A lot of the times the guest has booked thru a third party and are not aware of the no child policy. If the child is over 3 years old we charge for an extra person covering breakfast etc. We also have the parents sign on their booking form after I have written “as our child was not booked on the booking form we take all responsibility if anything happens to them and agree to pay any damages caused by our child. All guests are happy to sign. I hope this has been of some help. Cheers, Denise
