As ambitious as this is,
@analise please don't get your hopes up that you might accomplish this feat. There are currently over an hour and a half of rides open during morning EMH (just based on ride times, not allowing time to walk between them). And unless you are there during a truly empty time of year (are there any of these anymore?), not everything will be a walk-on. Seven Dwarves, Space Mountain, Peter Pan, and Buzz Lightyear tend to get at least short lines during EMH most times of year. And it is not good time management or planning to go on It's a Small World, Mickey's Philharmagic, TTA/Peoplemover or Carousel of Progress during EMH even though they are open (but if you wanted to, those four rides would take you almost exactly an hour if you hit start times just right for Philharmagic and Carousel - but don't!).
