We've had a lot of issues with guests booking our house for 2 people, then turning up with more. We've had parents turn up with their 2 kids plus an aupair but they've just booked for 2 people. I think people are assuming that children aren't included in a booking, but since they are using our bedding and utilities, I would argue that they should absolutely be included.
What is the best way of solving this issue? We have our listing set that it's an additional $20 for each person after 2. We're getting very tired of people not giving accurate numbers and then using all of our beds, towels, etc.
