I have a major issue with a "pay to play" aspect using common space paid by members through their purchase of real estate percentage, maintained through their dues. If I have reduced access, as compared to another member, then that is problematic and approaching a violation of our contract. Imagine not being able to access your own pool, not because it's being maintained or cleaned, but because a tiered membership allows access despite your continued payment into that common space. I can see an argument that places like the Epcot Lounge or Top of the World are not truly members only common spaces, but are members only accessible features. In that way, I can see a better argument that the feature is a "perk" and not indirectly and certainly not directly related to amenities in the contract.
Likewise the enhanced waitlist priority, or priority upgrade is problematic to the sentiments in the contracts that members are treated similarly when it comes to access to the unit. Therefore, anything that delays or increases access to a unit seems highly problematic to me.
Areas that are firmly in the "perk" area, free from indirect association with the terms and conditions of the contract, would be access to the park reservation system, access to an annual pass program, access to a dining plan, Genie + free days, options to purchase higher volumes of merchandise than current rules allow. In other words, these perks are not related to the access to the room or amenities of the resort.
Lastly, to the folks that are concerned we are wasting time and energy contemplating this program... DVC management over the recent years have tried multiple ways to increase revenue and not all have been on the "up and up" in the strict reading of the contract. (See multiple prior threads to review that well-discussed history) Some of the updates to "reimagined
point charts" were because folks like us took the time to ponder, perform critical analysis and respectfully communicate concerns.
