I personally think they have made WDW all hands on deck because they know by opening this before christmas and near the christmas holiday, they will draw even more people into these already extremely packed parks during that time. Makes complete sense from a business side, they know that there will be way more people willing to come to WDW then DL during the holidays so why not get this up and going. Especially since supposedly the DL version is not going as planned for them, I may be wrong but it makes sense.
