Howl-O-Scream at SeaWorld San Antonio, occuring annually since 2000. SeaWorld has hosted thier own version of Howl-O-Scream, containing a family friendly experience during the day, then becoming an adult oriented event during the night. In 2013, SeaWorld changed their recipe, in an attempt to become a contender with nationally ranking events such as sister parks Williamsburg and Tampa. Adding more Houses, Scare Zones, and raising the maturity levels were part of the new mix. For 2014, it has been confirmed that all three Howl-O-Screams will share the same theme.
