Valid point, they did get something Frozen-related into the parks without it taking 5+ years. There is also the Frozen show at DHS. Going the "cheap" route and doing an overlay of an existing ride and it taking 2 1/2 years after a movie was a monster hit isn't exactly something to brag about, though. It's basically giving TDO a gold star for giving the bare minimum for effort. IMHO.
(Not directed at anyone, just to be clear) So in the past 15+ years (?), they managed to get one monster movie hit into the parks with more than a M&G in less than 3 years. And Encanto isn't on that level, not by a mile. (Anyone with a young daughter during that time can probably remember attempts to get any kind of merchandise Anna and/or Elsa related was like a quest for the Holy Grail back then, especially an Elsa dress.
) Don't give me the nonsense about some song being #1 on the Billboard Top 100 as evidence this is a "cultural phenomenon". Plenty of flash-in-the-pans hit #1 and were insignificant within a few months. This movie isn't moving the needle like Frozen did. Sorry to burst any bubbles, but... it isn't. As has been mentioned, there are plenty of other Disney animated movies that could have been used in the parks and still haven't been. Just because a particular movie is your current favorite flavor of the month doesn't mean it should jump the line. And also, once again - Not every movie "deserves" to be in the parks.
