I believe most of that is sorted now, The Smiler being built in X-Sector was a sign they are aloud to be more noisy now.
I live very close to Alton Towers and people seem to enjoy it being there, The ropers are the people who attacked the resort in courts due to noise. I trust they do not live there anymore.
I agree with you how the resort handled it. I worked there last season and was there and involved in matters, I honestly feel very proud to be part of that team that day.
