Great article Evan, thanks for dealing with the unfavorable weather in order to bring a sneak peak to us before the park opens to the public!
I'll preface my comments below by saying I've never had the opportunity to visit KD (or BGW for that matter), so I can only go by what I see in pictures and video. Feel free to disregard my comments if visiting first is required to have any sort of opinion in your book.
Overall, it seems like they did a remarkable job. It's nice to see a park (and its parent company) take the time and expense needed to invest in the park's theme and atmosphere. There are a hundred different ways they could have saved money and still kind of got what they were going for. For example, the renaming and new sign for one of the rides on Candy Apple Grove. Helps tie the theme together, but definitely an investment that could have easily been cut "to save money".
Are the big apples and the Singing Mushrooms a little "tacky" or "too much"? Yes, to a point, I can agree with that statement. But, they are part of the park's history, and from what I've seen here and from the more general public on KD's facebook page, they are both pretty well loved.
As for some of the "new" food options - I'm less impressed. Auntie Anne's pretzels are pretty darn tasty, but I get those when I go the mall. Some of the other food options at KD are those types of mall food court/chain places. I get why the parks do it - it's profitable for them, and some guests will prefer being able to dine at a "familiar" place. But I prefer to keep outside companies/chains to a minimum inside the parks. I want to eat and experience something different there, not the same I can get at my local mall.
I also think the fake vegetable tops around the Spring sign is a bit much when you take into account he big ole apples and singing mushrooms. That money could have been better spent on foliage, topiary, something real.
