@Steve-Timothy0 You have to ask them to add other guests to the reservation. If the other guests alredy have Airbnb profiles, you can see reviews for these folks too.
If they don’t already have Airbnb profiles, they would have to create ones which aren’t really going to give you any information besides their name and could end up alienating the guest and causing them to cancel altogether.
Unless something is amiss, I don’t bother with this.
