I like the idea of earlier fireworks because it will give us a better chance to see them even if we aren't planning to stay late on all of our MK nights. However, as Josh on easyWDW stated, it is a departure from what Disney usually does in scheduling them later to lessen the crowd issues at the Hub. Hopefully, the added capacity can handle the holiday crowds at that earlier time. We often watch Wishes from Fantasyland so I don't know that it will really impact our group that much. We do hope to see the castle lighting show but I'm not sure what time that will be. I don't remember seeing any times mentioned on that.
I'm a little concerned about Disney still not finalizing park hours. It looks like they have changed them from 9 to 11 at the MK to 9 to 12, but still no addition of more EMH. I have read some rumors and speculation that Disney might be trying to cut back on EMH. I didn't really take much stock in it at the time but I'm starting to get nervous. We are depending on that 7 AM EMH to avoid the crowds and long lines and are hoping for at least one late night EMH. I'm a little nervous that the earlier nighttime entertainment is an indication that the parks won't stay open as late. I hope that's not the case. I feel like those early mornings and late nights help spread out the holiday crowds.
