I mean, I would hope you would be right, but I can't see why. This stuff isn't included in Maint Fees, or in the contracts themselves.
Disney is switching more and more rooms to DVC, this would be a great revenue stream for them. Heck it might even be to try and bring in more revenue from those rooms which sold on contract years and years ago but dues obv haven't been able to increase in price like Disney has increased the price of rooms.
I would think that even if these didn't apply to DVC on launch, I bet they would eventually, a year, 2, 3 maybe down the road. Maybe first discounted, and then slowly creep up.
But, I also wouldn't be surprised if they just applied right out of the gate. What are we going to do, sell our DVC packages ? Great, sell em, Disney doesn't care, as long as someone buys them, rents, them, shows up and pays the resort fee, Disney would be ahead.
