In using the app, how do I make add charges to add guest? Booking was for May 6 to 11 and decided Additional guest for 1 staying only 1 night on May 9.
As far as I know, having a different number of guests in one reservation is not possible. Technically, the guest could split it into two reservations, one with the correct number of guests for each date, but for just one night I wouldn’t do it.
Leave the reservation as it is and just charge the difference through the Resolution Center, as long as the guest is aware of the additional cost in advance.
Unfortunately, that option is usually not possible because the additional guest fee applies to the entire reservation, not just for one night. What you can do instead is message your host directly and explain that you only need to add 1 extra guest for a single night only. Some hosts may be willing to make a special arrangement or offer an alternative solution depending on their house rules and sleeping arrangement availability.
