How about behind the tower? I am currently doing this from my phone so no I don't feel like posting a photo but you are more them welcome to use Google Maps to see what I'm talking about. You keep going after the word overlay and that may be wrong word but it doesn't change the fact that at the end of the day a new ride COULD have been made and the Tower could have stayed or even be enhanced with new drop profiles and effects. This is a money making grab to sell more merch and put the IPS of now into Disney parks. It's shameful
Behind the tower is the last bit of contiguous backstage left for DCA. And even if a new 'space land' of some kind were put there we would STILL be listening to the gripes about thematic cohesion yada yada yada "wow, so we walk from hollywood right into space land, that sucks" "they should have built a third gate" etc etc
Trying to keep some you happy is an ever moving target.
Overlay is the wrong word. Its a reconstruction, a remodel, if anything, something else than an overlay. Lets at least use some terminology that is a bit more honest.
