As of today, Disneyland has yet to change their maps to reflect the change from Space Mountain to Hyperspace Mountain. As this point, I think it’s safe to assume the maps won’t change until late June when the Pixar Pier is due to open in DCA. It’s odd because the parks have changed the maps in the past for much smaller items/events.
***As always, I spoke too soon. Right after I posted this, I see a tweet from Disneyland that Hyperspace Mountain is ending June 3rd and it’s back to the normal Space Mountain. That explains why we haven’t gotten a new map.***
