Maybe you should try booking for a group of people, some of whom have a variety of ID in more than one name. You would quickly find that the whole business becomes extraordinarily time consuming when all you really want is 12 seats.
And the correct solution to that situation is to delegate the task to another member of your group! Failing that, ask them for their passports before booking and note down the vital information such as names, date of birth, passport date and place of issue and number before you book the seats because you are bound to be asked at some time for further info, such as for API or printing out boarding passes!
Or you could get them to sign a disclaimer saying they are responsible for all subsequent fees imposed on the booking after it was made because of insufficient or incorrect information supplied by themselves .....
