I just saw this on another site. There is an unofficial event happening this weekend that I was not aware of. It's Bats Day at Disneyland. It looks to be a goth gathering. I've been looking over their website and it doesn't seem that big that it will overly affect crowds, but it is worth noting. http://www.batsday.net/events/events.html#bditfp I will be in the park that day, so I'll be sure to report back.
