We went, we ran into by accident. My 3 year old niece enjoyed it very much. She kept yelling "Hi Mickey, it's me Emily" It was cute, but I wouldn't go out of my way to see it. But that's just my opinion.
We have seen it in the past and it is nice to see at least once. They do all the lights on the walkway and then it leads up to the tree. After seeing it a couple of times, I wouldn't go out of my way to see it but if I was in the area I would wait for it.
