One thing that the Disneyland space mountain building needs done is the removal of the magic eye theater below.
They really should open it up like it used to be. Put the stage there again, with tables and an eatery.move the entrance of space mountain over to the north side and have the queue start Inside the old arcade.
Tear down that large space consuming ramp they built on south side and remove as much of the building as they can along with the huge old America sings building.
That alone would open up a huge piece of real estate. The area where the pizza port or whatever it’s called now could be built out so that the first floor contained part of a queue for a large ride built on the real estate wasted by the Star Wars/America sings building.
The second floor area of the pizza planet could be designed so there was a platform for the rocket spinner
The perfect place to have a family ride for those guests waiting for people that are riding space mountain
