@Griya-Hanna0, unfortunately many hosts write with problems that are a little bit related to your story. They have guests who see the number of people who can be accommodated and only put in a request for part of the group.
Frequently these situations involve parents who book for adults and not for children. Sometimes this information is not discovered until it's nearly time for the vacation or when they show up at the door. For many reasons this is a difficult sitation for the host.
It sounds as though you were so looking forward to your holiday with your husband that you forgot that your kids were going with you....... who knows? but if you were going to a hotel, surely you would not forget to tell them that you were travelling with your kids as well?
It is a hard situation for you, and I hope for the best. In this case the host has no obligation to give a refund. This is not the answer that you want to hear, but ...... Maybe they will do a little more for your refund.... Dont forget that Airbnb will keep some fees and none of this goes to the host.
By your own admission you were responsible for the wrong information being entered, so unfortunately there is no cause for further refund at this point. AirBnb cannot force the host to make a bigger refund against their policy. That is the current situation.
One extra thing to keep in mind is once a booking goes through the host calendar is closed. Even when it is pending, the host cannot give these dates to another guest enquiry.
It may be that while your booking was pending and on the host calendar, they were forced to reject another booking and it cannot be guarranteed to be replaced.
Here is an example of what can happen with Hosts even though guests may not be aware:
"I received a booking for 3 days for 2 people at a tariff of approx-$280au. 6 minutes later I received a request for the same room, but this 2nd request was 4 people for 5 days and double the $value.
I screened and accepted the bookings in order, that is my etiquette consistent with Airbnb systems as well.
I cannot reject the first booking and then accept the 2nd because Airbnb blocks the dates on my calendar if I reject the first customer/guest."
So I now have an accepted booking with the first guest. But if these guests cancel, even if it is within a day, the other [2nd] guests are gone because I had to decline their booking.
If my first guest were to change their minds and cancel, I would be reluctant to offer a refund as my acceptance to the first guest led to my rejection of the 2nd guest, in this case a booking worth more than $double.
We all make mistakes, I sincerely hope this one will not cost you or your host too much pain and money.
So sorry about this situation.
Sincere regards, Christine.
