I know that Pleasure Island used to plan special events, and such on Halloween, but I have not heard about anything this year. I was there a few years ago and let me say, it was quite "wild". It certainly was a much more adult Halloween than MNNSHP. Not for children. It was fun for DH and I. We did not dress up in costume, BUT there were pleanty there for us to observe.. We did not pay any additional admission, they just had special enteratianment for halloween. It was great fun. I think if I were ever at WDW again, I'd spend it at PI.
