OC Auto show fundraiser

Actually, the Show starts on October 2'nd and ends the 5th, and I am going on the 3rd and have yet to buy my ticket. Will these tickets be honored on those days, or are they just for the 5th?
I already get MT mag, but if I get another sub with ticket purchase, I can just give the mag to someone else.
