The point is, you don't have to try to look for the recently built set of rides' show buildings. If I look long and hard, you could probably see the show building for HM through the trees. They tried hard to remove show buildings from site lines in 1971 and 1982 when Epcot was built, etc.I really take issue with this. If you want to see show buildings they are in plain sight in many areas. Hall of Presidents show building is clearly visible without any theaming above sleepy hollow. This presumably from when the park opened 50 years ago.
If you want to see them they are there, but if you choose not to “look for them” they are barely noticeable. I’ve been in Epcot numerous times this last week for the first time in 3 years, and can honestly say I’ve not noticed GOTG show building. (Or Soarin the last few visits)
BTW, I just went on Google Maps to see what you were talking about with regards to HoP. I do not see any sign of an unthemed part of HoP. Can you provide a picture of what you are talking about?
