A friend of mine that lives in a country where they don't use credit cards asked me to make a reservation for him through booking.com. I wrote his name in the first field, then, I selected "pay for someone else", then I wrote the name of the second guest.
I was surprised that the name of my friend did not show up in the booking confirmation. This booking is not free cancellation, and I contacted the hotel bu did not reply yet.
The room is double and can accommodate three guests.
Is it possible to add a guest without having to pay additional fee ow cancel the whole reservation due to my silly mistake?
