IllumiNations Cruise...Huh?

[Master Yoda]

You can be pretty confident the show won't be cancelled due to weather. It is practically unheard of with IllumiNations. As long as they can physically get the barges out to the lagoon during the day, the show will go. Now whether you want to be in a boat in severe weather is another issue LOL

On Christmas 2009 they did truncate the show a bit. There were incredibly high winds and while the music, lasers and fire went off, the fireworks stopped mid show.
