Howdy!
You'd probably want to keep the contact forms separate as there may be different people that own the task of following up with the attendee from each campus. If you had a single form, then you might have 6 different contact items for Children's Ministry, Volunteering, etc. At least when you have 6 different forms, you only have one choice for Children's Ministry, Volunteering, etc.
I hope this helps!
