With Volcano Bay, the CB towers, and Sapphire Falls welcoming tons of new guests to the resort; I can definitely see why they may be wanting to make massive changes to the way that the event works..I wouldn't be surprised if they wait until after Mardi Gras. I've heard those 41-straight nights may be a test.
Suffice to say, there's a LOT of possible changes to how HHN runs next year.
An question that should be asked though, would the schedule change to something like how Mardi Gras is seeming to go happen for not just UOR's HHN, but perhaps USH's HHN? I see it very justifiable that they may do that on both coasts, as both events have been quite popular.
