I don't think it's fair to say that they have 'made a meal' of Terror of the Towers. OK, the capacity and queuetime appears to be a major issue - but the actual attraction itself is good. No doubt they are working on the queue issues for the half term rush.
It is definitely the best overall Alton Towers 'resort' event I have attended, although I didn't go to Halloween in 2003.
We had an absolute nightmare in the tunnel as you probably heard Dan but we got priority passes as we complained.
I was very impressed with the whole of Scarefest, best park trips of the year for me. :)
