Its surprising what a lick of paint can do.
I have visited a theme park in Holland a few times, once in 2007, again in 2011, and most recently in 2015.
The first time i went, the place was a mess sort of halfway between the state the American Adventure was in and slightly worse than Alton towers with abandoned derelict rides, scruffy attractions and a fair bit of litter.
The Second time I visited it was like another park, the litter was gone the peeling paint had been touched up, previously rotten bits of wood had been replaced and the overall place had been improved .
The overall theme may have been, or is a little cheesy but the turnaround at Wallibi Holland was impressive.
Some of the previously 'broken' rides had been repaired and re-themed, the boomerang coaster became Speed of Sound, and the launched coaster became Xpress platform 13.
If Alton could replace the queue line from Rita with the one from Xpress it would be a significant improvement.
Another thing Alton has going for it is the House+gardens, without those there wouldnt be an Alton towers in the first place, at the moment these are criminally underused - especialy in the summer evenings, why not re-open the Swiss cottage and open the gardens and house in the evening for the paying public ( all be it paying less than the daytime thrill rides crowd) the National trust has made an art from of that type of stuff - i'm sure that there are also enough people that would buy a garden/house evening ticket and possibly pay enough to make a guided tour worthwhile of either the gardens, or a behind the scenes of a ride.
The waterpark could also do with a little TLC, on one visit I noticed a bolt on the floor in the masterblaster queue line ( the section with the nets) this had come from one of the side attractions ( ball bearing maze) When I alerted a member of staff to this they seemd a little concerned and said they would pass the message on - all that was needed was a replacement nut and a spanner to re-fix this. When I visited the following year the ball bearing maze was still loose on its bracket and still missing its bolt, there were other loose bits on the plastic railings on the steps up - also missing bolts.
