Check on disneyworld.com, under Studios park hours. Click on the date you want to check (if it's an EMH day it will say it), and it will list for you the parade time and Fantasmic times. The site goes out 6 months ahead so if you're planning within that window you're all set. Have a great trip!
I've heard this as well... and also regarding Spectromagic....
I checked my dates.. but no such luck... and it got me to thinking that Disney would NOT post these parade times on the website. Why? Because it would mislead the general public.
My guess would be you can find out by the time guide they give you when you get your bracelet... but I could be wrong?
