I wouldn't see why it would go, Disney Junior is horrendously under-represented at the parks and the Disney Junior show at DHS is probably the BEST show/attraction for preschoolers in my opinion. Just seeing the look on my son's (3yo) face during that show was magical as he sang and danced while watching his favorite characters live on stage.
That being said, they need to make sure it stays updated (if they haven't over the past few years). Jake and the Neverland pirates has been done for over a year) and doesn't seem to air as much as it used to, but Sofia, Doc and Mickey and the gang are still relevant (via Roadster Racers though, and tons of Clubhouse reruns).
They probably need to update it with the Lion Guard, and/or Goldie/Bear or Vamprina (though that is pretty new).
