Theme Park index of economic activity

Economists often refer to the "skip" index to determine the health of the British economy, i.e if they see a lots of skips outside houses it suggests that the economy is healthy because lots of people are spending money on renovation of properties.

On a global scale I wonder whether a better index is one of theme parks opening and closeing. Whilst we see a lot of closures in the U.K. and the U.S. (Camelot being the latest in the U.K), other areas of the world, such as the Middle and Far east, are seeing a large number of new theme parks being built.

It is hard to image any new theme parks opening in theU.K. at the moment, which says a lot about the wealth of the nation I think.
