Seaworld's Halloween Spooktacular begins today! It is included with park admission and great for young kids. There is trick or treating and Halloween activities, a sesame street Halloween show, and "Shamu Rocks" which is the nighttime Shamu show only performed on special nights during the year. The event is every weekend in October as well as Friday the 29th. Its a great event, Kid can even come dressed in a costume! I would definitely check it out!
