I think the point is that Twycross attracts 500,000 visitors a year without much effort, regardless of whether the enclosures are up to the required standard. It does that because it's centrally located, easy to get too, family friendly and it has a personality, based around its past ownership and association with the PG Tips Chimps etc that appeals to a lot of people.
Of those 500,000 visitors, most of them are pretty ignorant as to what is a good enclosure and what is a bad one, what constitutes excellent animal husbandry and what doesn't. I spent a year walking around the place, standing in enclosures with people hearing comments like 'Aren't they well looked after' a million times and 'Look at the Monkeys' when stood in the Bonobo house. These people are the bread and butter for the zoo and Twycross is so well placed to increase visitor numbers massively, they have to take advantage of that because if they optimise visitor numbers then they maximise revenues and they have the maximum amount of cash to invest in (fingers crossed) really great enclosures.
I'm willing to bet that most of these people think Himalaya is bloody brilliant and they don't care that they have to walk through it to get in to the zoo, and the kids probably love the wristband because it's a memento of their day, they probably keep it on for a week afterwards! Himalaya massively improves the visitor experience for all of these people, their negatives about the zoo prior to Himalaya would have been sat in my car queuing to get in, crap toilets, couldn't get the buggy in the restaurant or the shop, had to stand in the middle of a road in the pouring rain to pay, but these issues are solved by this building.
We all know that they have money in the bank, they can spread that thinly across the whole zoo now or they can use it to put the infrastructure in place to attract and cope with many more people and then do it with more funds behind them. The money they have now wouldn't go that far if they wanted to build exhibits that equal Himalayas standard, what did Realm of the Red Ape cost at Chester £3.5million?
I'm not saying that I agree with absolutely everything about Himalaya, but they have taken best advantage of private funding, created a spectacle that will bring in more people and improve their experience of the place and I hope that will in turn help to bring the money in that will enable them to do something special with the rest of the zoo, and satisfy you guys on here who are serious and passionate about zoos and the way that they look after their animals.
