Undoubtedly there is a grain of truth to this. Some of the things mentioned in the first couple paragraphs of the story are consistent with member surveys and other leaks over the years. Things like "Enhanced Park Access" and "Expanded Access to Members Only Spaces" strike me as clear value-added offerings. Disney hasn't announced any long term plans for Extended Evening Hours. This could be
DVC's way of trying to subsidize continuation of that perk as a recurring DVC-only.
Certain elite perks would require an elite cost to make it worthwhile. But I don't see that as being the goal here. This seems more like a group-buy situation. If 200k members agree to spend $100, that's $20m annually. Can you fund a second theme park lounge and some amount of DVC-only park hours--plus a few random ticket offers and other low-cost perks--for $20 million? Probably.
Things spin a little off the rails when speculating that TOTWL access, AP discounts and free lightning lanes could be part of this tier, along with priority access to DVC reservations or Moonlight Magic. That's all wild fantasy and not worth getting worked-up about, IMO.
