I hope you don't mind one more question. We bought points on 5 different occasions, most resale, but the last purchase was in 2012 or 2013 (Can't remember which)-certainly way before 2016. Should we be concerned about ever having resale restrictions? Or are we grandfathered for life, regardless of us selling anything?
If you purchased resale in 2012 or 2013, you do have the resale restriction that prohibits you from using resale points to trade out for reservations in anything in the Disney Collections, one of the membership extras.
If you are asking whether, even if you kept all those prior resale contracts, you will always be entitled to other membership extras far into the future, the answer is yes with one exception: DVD could legally take away any membership extras from all existing members even ones who purchased directly from DVD, e.g., (a) it "suspended" pool hopping among the
DVC Resorts during the pandemic and that member benefit may never return; (b) in the 1990's and early 2,000's a member could purchase length-of-stay park passes at a discount and that was done away with, after which DVD adopted an Annual Pass discount. In other words, it cannot do anything to take away more membership extras from resale purchasers who purchased before April 4, 2016, unless it also does away with the benefit for direct purchasers.
What DVD most likely cannot legally do is decide that resale contracts purchased before January 19, 2019, have no right to reserve the resorts begun after that date. That is the effective date, announced before it occurred, of the rule prohibiting resale purchasers from reserving resorts opened after that date. The POS's of those pre-2019 resorts provide that owners, both direct and resale, can reserve an unowned-DVC resort, including any added to the DVC reservation system in the future. DVC cannot change that rule for any pre-2019 purchasers, direct or resale. There actually remains a continuous legal issue as to whether that is even legal as to 2019 and after resale purchasers of pre-2019 resorts. The terms of the pre-2019 POS's indicate that no such restriction is allowable even as to any future resort added to the DVC reservation system after 2018, but DVD may have a possible defense as to post-2018 resale purchasers raising the issue since they purchased with knowledge of the restriction and thus possibly waived any claim to avoid it.
