The key is still there. I remember last year I looked and it was there.
Another secret is near the back of the park (don't remember exactly where) there is a umbrella hooked onto a street lamp. If you pull on it, it starts raining! It was a lot of fun, my little cousin was wanting to go back there all day.:lol:
The only time I've ever *not* found the key was the one time I went soon after they had re-carpeted the entire pre-show area, and they hadn't re-installed the key yet.
Nothing was inside the boxes, and sadly PropShop- where they were, has been refurbed and they are all gone now. And while the Singin' In the Rain umbrella is still at the end of NY Street, it no longer rains when you pull on it.
