When does 10-day PH ticket expire?

[Volksjager]

Can you use a 10-day PH pass over 14 days or does it expire 10-days after 1st use?

The ticket would expire 14 days from first use. We usually purchase the 10 day parkhopper with WP&M options and stay longer than 10 days and have never had a problem.

They expire 14days from first day of use.

... and the day of first use is Day One. In other words, it's not 14 days AFTER the day of first use, it's 14 days from that time but the day of first use is the first of those 14 days.

In other words, if you first use the ticket on August 1, it expires at the end of August 14.
