When they first build Disney-MGM Studios The Earffel tower was pretty prominent along World Drive. You barely notice it any longer because of the trees - they've grown over the last 25 years.
You don't really notice it in the park, either. It's off in the back. The best place to see it was on the tour which is gone. You could kind of make it out along Hollywood Blvd as you entered the park but, again, it's not prominent.
It was neat but I don't think most people will notice it's removal (people here will, I'm talking about average guests).
