Fun Fact - Yes, you can really see the Tower of Terror from Epcot. If you stand just about anywhere between the Mexico Pavilion and Disney Traders, and look toward Morocco, you'll be able to see the Tower of Terror in the behind the Morocco Pavilion.
Disney Imagineers knew this when they built Tower of Terror so they added Minarets to the Tower of Terror to make it blend into the background as if it was intended to be part of the scenery. No other Tower of Terror building has these Minarets.
To get this shot, I had to yes my longest zoom which is a 200m focal length (1.5x crop). I used an f/8.0 aperture to get good clarity throughout the shot, ISO100 for minimal noise, and 1/250 sec shutter speed.
Have fun capturing the magic of Disney.
