The rumor I heard on the hotel was that it was supposed to be the first to have an entrance directly into the park (somehow), so the pathway would be used for "after hours". I never put a lot of stock in the rumor since any hotel entrance into the park would have to cross the canal and several backstage areas. NOt particularly practical, but it could happen for the right amount of money. Then again, guests would probably pay a premium to have direct access into the Magic Kingdom from their hotel.
