Yes, you just have to take it in the park and redeem it before that date. It is not the actual pass, jsut a voucher for one. If you end up redeeming it at the park after that date, they will still honor it but you will have to pay the difference if there has been any price increase. There was a price increase this week, so if I were you I'd run to Vons and buy those puppies now while they cost the old price!
