SeaWorld Orlando says those visiting every weekend in October will find “silly, spooky fun at Halloween Spooktacular.” During the daytime event, families will be immersed in an underwater “fantasea” filled with trick-or-treating, dancing with sea fairies and pumpkin fish and sea-themed arts and crafts. SeaWorld’s Halloween Spooktacular takes place Oct. 5-6, 12-13, 19-20 and 26-27, from 12 to 8 p.m.. Halloween Spooktacular is included with park admission.
