Thanks for the advice. I am sure the information is correct, I'm just not sure how effective the system is in terms of the ID as, judging by some of the requests I've received, under 18s are managing to create accounts quite easily and if they can create an account, I assume they can also make a booking.
It's not been a problem for me so far as most of these guests have disclosed their age in their initial message. They did not even realise that it might be an issue! They don't read the listing properly, let alone Airbnb's T&Cs.
I'm aware though that it could be an issue in future if a guest isn't totally honest. Yesterday I got an enquiry from a lady who was trying to IB but couldn't and didn't understand why. I explained that her enquiry said 1 adult + 1 child and that I don't accept children. It turns out that she was bringing two under 18s with her, so she hadn't even put the correct number of people on the booking.
Once she realised she couldn't IB with a child, she changed the booking to 2 adults, even though I'd already told her no. She still couldn't IB. I guess she must have had a negative review or something else that prevented the booking. So, she contacted me again and I had to reiterate that A. I don't accept under 18s and B. the room is for maxiumum two people. It's funny because her reasoning was that one of the girls was 17, so counts as an over 18 anyway, and the other was 13, but tall, so should also count as an adult and my other guests would not notice there was a child in the house!!
Now, the same guest, had she realised in advance, could have booked the room for two adults and not told me the number or age of her travelling companions. I wouldn't have known she was bringing two teens with her until they turned up at my door. I would have then had to turn them away and contact Airbnb to cancel the reservation. It would have been bad for them and bad for me to then have the room empty in high season. All round, not an ideal scenario.
I really think that if Airbnb is going to have rules like this, they need to be more stringent in enforcing them. Who is checking the guest's ID? If their ID says they are under 18, why are they able to still create an account?
