We are going to to Islands of Adventure in October on a Friday night that has one of the Halloween parties at Universal. Does that affect the crowd at all during the day at Islands as far as it being much busier than usual? Also I see there is a Express Plus pass that you can buy for $15 that basically gives you one free pass per ride. Is it worth it, or isn't it necessary on a Friday during that time of the year?

We were there last October. During the day it was not crowded at all. Can't tell how it was at night though.

15 dollars is alittle extreme to be only able to express to the front of the line only once.
