Instructors? That only applies to Novice anyway right? Maybe offer a discount or even a free day to a select few with lots of experience like Brian, Monte, APCH8r, SJC, Zorro, Flounder, etc. So that they can offer tips or a tow to those that really need it. But if your dude can provide a few instructors then nm. It depends on what kind of showing we have. My first day at Nelson wasn't a beginner's day, it was open practice. They didn't split us up until halfway through. Luckily I had an instructor but by the end of the day he just sent me out. It really wasn't bad if you don't go out there trying to catch everyone.
