Believe me, if you are responsible for feeding a group, whether it be a potluck, a host-prepared meal, or a catered meal, you notice. Lots of other folks will notice as well.
Personally, I like the idea of bracelets, just like a music festival. Pre-registered attendees get non-removable bracelets. If food supplies warrent, non-pre-registered guests can pay for a bracelet on the spot. If food supplies are limited, late comers are simply out of luck.
I am going to suggest the bracelet idea for the 2007 Texas Vintage Rally. With an expected 100 rigs and at lest one catered meal, we will have to set up some controls. We certainly will not recognize everyone by sight. I fully expect that some non-pre-registered folks will appear.
