SW ticket question

[glovergirls]

I am looking at the seaworld website and it says when you buy a regular ticket you get a second day free to use anytime before 12/31/09. Now heres my question. I noticed people selling tickets on ebay with a second day left on them. If I buy this do you think I can use them or it will be a problem.

Thanks for the help I am just trying to stretch our dollar as far as I can.

I don't know about those tickets, but for the season passes they use the same biometrics/finger scan as WDW.
