Disney is gonna come out of this smelling like roses regardless. Even with poor reliability.
Say worst case, it Evacs media on multiple rides, etc etc. The articles will say it’s having issues “but when it’s working it’s the most amazing thing I’ve ever seen in my life and will make you a believer and blah blah”.
If it doesn’t evac it’ll also say it’s the best ever.
This is Disney’s chosen media folks we’re talking about. They’re being wined and dined currently and will trip all over themselves to gush about whatever product gets put out. Even if it’s a colossal disaster, it’ll still get amazing feedback with the only caveat being “give it a few weeks to work the kinks out” as if people were going to book a trip for Christmas at Disney this week.
Anyone who thinks Disney is going to have egg on their face is sorely mistaken. Deliver a quality product, own the media, then sit back and reep your rewards.
