I'm not (really) surprised, but the season pass prices will be going up after May 31st! I actually thought they would stay the same all year this year, since they didn't go up over the off-season at all.
You can buy them
here, $69.99 for the Play Pass (no Safari), $79.99 for the 2-Park and $99.99 for the 3-Park.
Expect the prices to go up by $10 a piece starting June 1st.
