The GDGO is looking into an Ace Race to raise cash for trees, so I've read quite a bit about them. If you do the official Discraft Ace Race, you can't charge any extra money, even for additional value (like included lunch). Any extra funds have to be raised through side action, sales, raffles, etc.
I think it would be hard to run an Ace Race on an open course with any sort of casual traffic.
