We have a number of fundraising events that we will be doing that we will be charging per couple. Is there a way to capture both names so the we can print a list, and possible name tags?
While it's possible to configure an event page to allow people to register that they are bringing guests (see screenshot below), it's not possible to collect personal data on two individual RSVPs at once.
If it's imperative that you collect all the signup information for both attendees, your best bet would be to turn off "Allow guests" and ask them each to sign up independently.
Another option would be to personally follow up with each RSVP who indicated that they'd bring a guest and manually enter their "+1" into your nation as an RSVP.
