Hi Peter,
Thanks so much for reaching out!
With each additional ticket, additional attendee is usually required by default for each one. This is so that information can be added for each additional attendee.
You may be able to remove additional attendee information with a customization on your part.
I’d recommend starting off by taking a look at our Themer’s Guide, which can show you which templates can be edited and copied in order to achieve the results that you are looking for.
If this functionality is a requirement for your intended project, I’d suggest that a third-party developer would be the best way to make this feature happen on a short timeline. ? We maintain a list of developers who work with our plugins on our Knowledgebase here:

Let me know if you have any other questions on this topic!
Thanks,
Jaime
