Continuing the entertainment cuts for the start of Disney’s fiscal year, Rafiki’s Planet Watch will be going seasonal. The last day will be Sept 29th, no announcements yet as to when it’s seasons will be.
You have to assume the train will stop too, no point in running it to nowhere! And that is likely the biggest cost. It also means the meet and greet will go too, that’s Rafiki and Doc McStuffin.
Again, this was a thread on WDWMagic. Source is reliable though. And WDWMagic will have something on it’s news section as soon as they get it confirmed.
Edited to change heading.
