How does the expiration on PHs work?

[Momof4girls]

I'm trying to sell our remaining days since DH took off with our PHs mid-week and we had to buy new ones.

Our first park day was 2/25 - we went to the park that day - do these expire Friday of this week or Saturday?

I think it is 13 days after the first day of use. Friday...
You can exchange them at the ticket window for an annual pass and pay to upgrade..

Oh no! Didn't you just have that other upgrade problem and now this??? That's crazy!! I would have had him overnight them and skipped a day!

Yes it's 13 days after first use so I don't know that you could sell them!
