Theme park trips are so dang expensive I get the urge to try to wait till things are perfect. In general, I struggle with "all or nothing thinking" (as my therapist used to say) in many aspects of life. I've been trying more recently to let things be imperfect and embrace the grey areas.
To be fair, I think I still would've had a mini breakdown if Stardust was closed or not dueling when I was there, so I can't act too enlightened. But I never saw Monsters Unchained run perfectly (the Frankenstein that grabs the electricity nodes was down, which doesn't seem that common from all the talk I've seen here), and I still think it's the best dark ride of the modern era.
Downtime is the tradeoff for ambition. Maybe there were a couple moments where they could have developed a more satisfying b-mode, but I'm glad they took big swings with this ride.
