Fortunately, the tiki is far more friendly than I had anticipated. However, I had hoped that Disney would have some of their sculptures go back over the rock work and improve it to better resemble the rock work outside... and add in more whitewater so we can see it cascading down. In photos it's not looking like a fountain at all.
Now that the conversion is complete I'll give it my grade: It has earned a solid C. My reasoning, in this age developers and artists are able to achieve so much more than ever before. They could have ripped out the the old fountain and created this at any point in time, including back when the resort was first built. There is nothing "wow" about this. Nothing to write home about.
What would have earned an "A" with me? How about digging out a channel in the tile so that, like with WL, it looks like there is a stream flowing from the front to the back of the resort? Add in bridges and make it feel like the open air resorts the Polynesian islands are known for by mimicking some feature of nature.
A "B" would have been to create a narrow ceiling to floor cascade on a glass-like substance -or- something with some kinetic energy to it (No, I have no ideas here, but I'm sure there are artdy people out there would could envision something amazing)
