Any good ideas on how to track an RSVP what has more then one attendee RSVP

The need is to send an event email out to a stable email list of 400 people. We need a good RSPV number, but each person, at this event may/will bring up to three more guests. people who will not be CC contacts.  CC does not support a way to select a number of attending in the RSVP function of the email.  We're going to be doing a number of these events and it's starting to feel like CC is moving away from event coordination (they dumped the name badge printing function a while back, which was one reason we started using the software a while back).

Right now, I am putting a section after the RSVP block asking them to PLEASE email me separately if they plan on bringing more than themselves. It's cumbersome. I am not a power user, but I really like CC.  Other products do name badges, RSVP census capabilities, and general event organization better than CC. I just don't want to move on if I don't have to. Does anybody have any suggestions or workarounds?  

Thanks for the help on this.
