I have to admit, while my kids love meeting Ariel, I have no clue what a mermaid has to do with either the Matterhorn or Tomorrowland. It's a great meet n greet, highly themed in and of itself, but completely out of context when you step back and look at everything. That said, now they want to tear it out and put a giant teapot in it's place. At least with Ariel the meet and greet was semi tucked away and not overly noticeable. I give WDI the benefit of the doubt, but I have a really bad feeling about this one. The only spot I would think that would have been PERFECT is now a smoking pit (motorboat lagoon). Option B would have been on the right side of the parade route as you are looking at Small World... a spot used only when a parade is going, or in the rare event of a character meet n greet. If they could somehow place it in Fantasyland, say by taking out the wagon in front of Village Haus... that would have been even better. But no, they are placing it right where Ariel was, and in full view of everyone... I guess the future is full of tea and giant teapots!
In any event my little ones won't care, they will drag Daddy to meet Tink and her flying friends... but for me it is yet another stunning example of "make it fit" theming.
