Well, I did some poking around and we could get a car that could reasonably hold 5 people for about $160, which is after sales tax, but I don't know if there are other fees that would apply. Aaron has a bunch of coupons so we could probably knock at least $25 off of that, probably a little more. That would be from the Enterprise which is near Stonestown (walking distance from the SFSU campus) from Friday noon until Tuesday (most car rental places are closed on Monday so the return would have to be on Monday).
So, with the coupon and all it would probably work out to about $50 a head, less if Dave and his friend chip in. It seems worth it to me, how about you guys?
