How are the crowds in middle Oct 11-19th? We're splitting days with US/IOA and WDW and throwing in a day at Seaworld :dazzle: :ROFLOL:. With Columbus day being Monday the 13th, I was wondering what would be the best park to attend Sunday. I'm thinking Seaworld pretty much all day. I've seen where this is also a day for their Halloween event. Has anyone attended Seaworld's Halloween party? From what I can find, it is included with standard admission but other than that, I can't really find much more info.
