I personally think this is an obvious example how the people are trying hard to make Everland something like Disneyland. As for me as a tourist, I would be looking forward to seeing something more Korean. But then, the park could be developed for the Koreans and not foreigners.
There were a lot of dancers dancing to the loud music and also colourful floats. The whole thing took about 30 minutes and I was hoping for Mickey Mouse and Donald Duck to appear but there were other animals instead. :)
