Er Tussauds are owned by Dubai Investment Capital, hardly a poor company, and I don't really see how the UK park industry is in a bad state, one park has closed recently and thats only because of Amanda Thompsons awful management, Southport was on the up a few years ago, now when Amanda Thompson takes over it fails.
Apart from Tussuads, there are currently Flamingoland, Oakwood Drayton Manor and BPP who aren't doing badly financially. Infact the only major park I can think of which is failing badly is Lightwater Valley.
