I totally agree with Mackem. Like I said, at Cedar Point, you can easily do every coaster in one day, and usually get a couple more than once. With more queues, the lines end up being shorter. Had I not purchased shortcuts and speeding tickets for Electric Towers, I would have never wanted to go back to AT. And, its not like they have a LOT of rides. Its really a catch 22 situation.
True, but you did attend on the busiest weekend of the entire open season. If you attend the Towers most of the time, you can do all the rides and do repeat rides at the end of your day.
However, I haven't really posted my views yet - so here goes!
I think that Alton Towers could use slightly more rides, however I would have no particular desire to see a sudden emergence of a dozen new rollercoasters. Parks such as Cedar Point and Magic Mountain, who have a lot of rollercoasters, do not spend a great budget on theming and landscaping. At Alton Towers, aside from Rita - Queen of Speed and Spinball Whizzer, all the coasters built between 1992 and 2002 had a high landscaping cost, and for the most part, a decent theming cost too. Think of Runaway Mine Train's theming and tunnel extension excavation, Nemesis' pit, Oblivion's hole and Air's tunnels. John Wardley is quoted as saying the Americans thought it was 'mad' that Alton spent 1/2 Oblivion's budget on the hole.
I could envisage that with a sudden mass of new attractions, that the attention to detail would be lost - and we would see more Rita/Spinball-esque rides coming through. No offence to Cedar Point, whilst their attractions are undoubtedly some of the most, if not THE most, thrilling on the planet, looking at some of the pictures, they don't always take visuals too seriously - but then again, that isn't what they are about.
I would like to Alton Towers slowly increased its portfolio, as it did through the 1990's. This way, we can see healthy budgets for both attraction and landscaping/theming. I would much rather see an RMT/Nemesis/Oblivion quality attraction every 4 or 5 years than a new Spinball every 2, for example.
If Alton Towers had 2 more rollercoasters, a couple more flats and perhaps an extra special new dark ride, along with a show or two, I think that the park would certainly have enough for two days. I think the public ENJOY re-rides, re-riding your favourite's is part of the visit.
So all in all, I don't think 20 coasters would ever be of benefit to either the park or the public - operating costs would spiral and the park would have to re-coup this through massively inflated admission charges, above and over what the charges already are. But with a handful more rides, the park would probably seem complete.
