Alton already has everything it needs to make a fantastic event, they are not just utilising it as they did in previous years. For example:
Duel Live or Hex Live (Duel live was excellent when they ran it with the 5/6 actors inside)
Haunted Hollow (though its a great sadness that actors were assaulted) - maybe some atmospheric lighting, sound effects etc
Lighting, Lighting, Lighting!!! Key to everything. The red lights on Nemesis, Blue on Air, Green lighting along paths, Green writing/lights on the walls up to Hex, lighting around Thirteen, smoke in the queue line around 13 and on the Rita launch, and the Smiler this year opens up all prospects of fantastic lighting opportunities. The jeep in Katanya Canyon used to be lit up green, and the skeltetons would be seen floating around the rapids.
As for the mazes, I dont think we need more, just more effort put into them, though saying that, ToTT was very good last year and the Sanctuary in May this year was excellent. They need to keep the lighting and atmopsheric lighting around the queue areas. As for CoS, last year I didnt rate it that much, the props looked dirty and the set was tired. If they inject a bit more effort, get the music playing around the queue area, the hay bales, make it feel like you are actually queuing for a weird warped circus tent.
As for Zombie Scare Zone, I enjoy this each year, smoke and lighting again is key as is the number of actors inside the zone.
They need some characters walking around the park, in particular around the ToTT and Sanctuary queues like in previous years.
And lets not forget Halloween music all the way down through Towers Street.
As for the hotels, while each year granted they are decked out nicely with lighting, there wasnt even any Halloween entertainment on the ship last year. Previous years I recall the band and singers being dressed up for the event singing "spooky" songs. Bring this back!
Everything is there for Alton to use - just depends if they can be bothered to make the effort.
