I usually pre-register for foot races, just because the commitment gives me motivation to train and run.
For overnight cycling tours, usually pre-registration is required.
Not so much for day rides. If the weather's crummy, I won't ride, I'm a wuss, I'm only riding for fun and nasty grit is not my idea of fun. So I'll eat the $5 or whatever pre-registration discount and just show up on the day-of.
But a charity ride, I would think that (1) most of the financial support should come from corporate sponsors, not riders, so the "lack of support" probably has more to do with the organizers not doing their job, not you; and (2) pre-registration is usually required so that people can donate online, riders can meet their minimum donations, etc.
ETA: Now that that much of the work's been done, why not turn this into a fundraiser for YOUR club, on a later date? I get that there's still a LOT of work involved - marking the route, arranging insurance, sag service, etc. - but it would be better than letting your planning go to waste, n'est-ce pas?
