Here's the times of all the "different" shows from this Saturday just gone - didn't go to any of them unfortunately as we were only at SeaWorld for half a day (our flight home was in the evening).
Clyde and Seamore's Ghostly Pirate Cruise - 11:15, 1:00, 2:00, 3:00, 4:00, 7:00
Creepy Creatures at Pets Ahoy! - 12:15, 1:45, 3:15, 5:00, 7:15
The Monster Mash Costume Parade (Bayside Stadium) - 12:00, 2:00, 3:30
Shamu's Haunted House of Douse (replaces Shamu Rocks America) - 8:00pm
"Arrg! A Halloween Thriller" (Bayside Stadium) - 8:45pm followed by firework display.
Hopefully the times should be roughly the same for this weekend.
