Why?oh I know...it was sarcasm. I'm so sick of up-charge events.
If you don't like them, don't pay for them.
I could understand having an issue if an event like this closed an attraction early or made it's opening later in the day, but the most this event might do is slightly increase the opening wait time of an attraction most people here would use a fastpass for or does not have that long on a line to begin with.
