It's with regret I agree here - I spent 20 years working in the park and I slowly watched the 'themes' disintegrate into..well, in all honesty, a bit of a sloppy mess of rides here and there. It was always supposedly on the cards, but no-one ever actioned anything - especially Gold Rush and down around the Wiggles World/Tiger Island/TOT area. Unfortunately, the theming problem is as vague as the entire park and as specific as queues - take the Cyclone or the Giant Drop for example - there is no atmosphere whatsoever anymore. People just aren't as pumped as they used to be. The queue is an integral part of the experience and the only ride I ever felt came close to offering that atmosphere was the TOT - although the skull never really made sense and it was often a talking point of staff.
