If you guys are serious about renting Enterprise will let you rent a van if you are at least 21. However, if the driver is 21 to 24, they charge an extra 15 dollars. So for a 7 passenger van it'd be about 86 total.
Alamo won't let you rent under 25 unless you've got a corporate contract or are part of an international tour.
National's underage charge is only 10 dollars, but the van itself costs more so it comes out to be 87.
Budget is the only place around that has the 12 passenger vans, but doesn't let anyone under 25 rent a van, truck, or SUV at all.
All companies mentioned have locations in Champaign, mostly near Neil and Kirby. Prices are to rent a 7 passenger minivan including tax and underage charges, but doesn't include additional things like insurance if you're into that sort of thing.
Yeah, I kinda got a little bored sitting here at home. Plus none of this matters if two of Andy, Brickman or me will be driving. I think Dave S has a car too, at least he did last year.
