Hi, I've been searching around sites looking for any news about Seaworld. I've seen a report that there was a fire in the carpark last month but can't see any details about what happened. No reports anywhere except on doingflorida.com (news dated July 19th-with pictures), I even looked on The Orlando Sentinel page and couldn't find anything!
A car fire isnt going to make local news unless it stops traffic OR it has people in it. Probably the reason why you didn't find much on it. It's not news. I'm sure if the news here in Orlando could somehow use it to blast these parks, they would.
I was there that day. It looked like it was just a bus that caught fire and damaged one of the canvas roofs a little. It was no big deal as far as I could tell.
