Is it Mermaid Lagoon? or
Is it Robert's article about Mermaid Lagoon? or
Is it MermaidMelissa's use of this article for shameless self-promotion? ;>)
When I visited the park a few years ago, I ran into one of the members of the development team and his wife, and had a very pleasant conversation with them. (In a park filled with thousands of asians, the few westerners tend to gravitate towards each other, and you have conversations that you would never have in American parks.) They were on their 108th visit (or something close to that number) to the park since it had opened and were just as enthusiastic as the first time.
By the way, they were also very aware of Theme Park Insider.
I was in Tokyo but unable to visit this. I have friends who worked there as the characters too. The reason I like this write up is because I also perform as a Realistic Mermaid. Love, MermaidMelissa dot com
