You should check out the SeaWorld web site, I know they extended the offer on their "funcards". For the price of a one day entry you get unlimited access to the park until Dec 31st. You print the voucher on your own PC and take it to the office by the main entrance to SW. You get a ticket like a credit card with your picture on it. I believe you need to bring photo ID with you, but the info is on the website.
