Summary / TL:DR: This article provides instructions to add additional attendees to a conference in Advantage.

You can add additional attendees before the order is posted and after as well. This can be situational based on the details listed below:

The Conference Registration screen allows you to record any number of attendees under a single registration. There are two reasons for entering multiple attendees under one registration.

The conference charges for all the attendees are being paid by one bill-to customer
The attendees want to take advantage of volume pricing offered for a conference. Volume pricing operates only within a registration

Circumstances in which they do not know if other people are attending would be the deciding factor. If they know up front then it make sense to add them during the order process before posting.

These instructions require you to have a control group open. For more on control groups, go here.
