This is sticky. Here is the full sentence from the bold type paragraph regarding Membership Extras: "Disney and Concierge Collections options are not available for ownership interests not purchased directly from Disney Vacation Development, Inc. after March 21, 2011, and, effective April 4, 2016, Members who have not purchased an ownership interest directly from DVD will not have access to Membership Extras."
Initially, this sentence just appears to reiterate that resale points have not been eligible for making Disney and Concierge Collections reservations since March 21, 2011. But then it adds that a new policy change took effect on April 4th (adding more restrictions regarding resale purchased points). It states that as of April 4th, the change which went into effect is that "Members who have not purchased an ownership directly from DVC will not have access to Membership Extras." It does NOT actually say that only NEW members after April 4th do not have access, but that MEMBERS who own no points purchased directly WILL NOT have access, and this went into effect on April 4th.
I see no reference in this document to any date on which resale purchases were made making ANY difference. There is no mention of grandfathering in existing Members who have owned only resale points for a long time. If someone does see written evidence, please share. Remember, no matter what anyone says, only the written documents can define how this will play out.
First positive: If this document tells the whole story, then a small add-on of points purchased directly from DVD would provide the Member with access to Membership Extras. That would be similar to how several other timeshare companies have handled this. It encourages existing Members who have not added to their holdings in a long time to step up and buy. Other companies have followed the removal of benefits from resale owners with a subsequent increase in the minimum number of points allowed for an add-on purchase. So if DVC currently permits as few as 25 points for an add-on developer purchase, they may raise that in the future. Just a heads-up.
Second positive: Someone posted a question about whether resale Members would pay dues which would subsidize the Membership Extras for others to enjoy. In the paragraph following the bold type paragraph, it says, "No costs of acquisition, operation, maintenance or repair of the Program or any Benefit are passed on to Purchasers as common expenses of a DVC Resort or the Club." This suggests to me that your annual dues do not contribute to these extras. With most timeshare companies, the cost of developer perks and benefits is covered by the sales department. They negotiate a low cost and the benefits are used to boost sales so it may be taken as a business expense.
Unfortunately, if this document is the whole deal... it does not look good for anyone who only owns resale contracts.
