I wasn't an MVC owner or very active on TUG in 2010, so I don't know how that was disclosed, but at that time MVC was a very small part of the much-larger Marriott International, so I would suspect that any discussions with investors about the timeshare operation in the earnings calls would have been very high level at most. Now that MVW is independent and a 100% pure timeshare play, they talk about that business at a more detailed level than when it was part of MAR.
I would not expect the Investor Day info to be the kind of announcement that would trigger tigger dates and stuff like that. It will likely be the high-level, strategic directional stuff that dominates investor presentations. I wouldn't expect any cut-off or qualifying date to be set until very close to the operational roll-out announcement of whatever they do. But who really knows? Just speculatin' here.
Prior to the 6/20/10 overnight announcement of the implementation of the MVW Destination Club points-based timeshare product, there were YEARS of rumors spurred by occasional targeted "surveys" from corporate, unsupported assertions made during sales presentations that in true TUG fashion were dismissed by many as gibberish intended to spur sales, and vague allusions to something in the pipeline during prior investor calls. NOTHING related, no branding or product or Weeks affiliation or legal documentation or ANYTHING was officially released until that after-midnight wholesale change. The announcement basically consisted of an email blast (that didn't hit every target,) and, a blurb on the owners' website with links to the contact information for purchasing DC Points, the legal documents, and, basic information about enrolling existing Weeks (eligibility, enrollment fees and DC Points allotment amounts for the Weeks in our individual accounts.) MVW didn't even offer a basic FAQ at the outset; that came later and appeared to be a Hail Mary pass because their phones were overloaded with calls from owners who had no idea what was going on. TUG was literally the only site online where information was being disseminated to the masses (and that was proven by a few people who tried to cash in by selling TUG's good info.)
This isn't meant to irritate the Vistana people who think Marriott people are too invested in the discussion of how Vistana might integrate under MVW's umbrella but, whether you (the collective) want to acknowledge it or not, it's not a stretch to say that the people on TUG who were involved in all that speculation were instrumental in gaining as quickly as possible all the information about how the DC works and how to best play the new game. Literally HUNDREDS of posts turned up overnight following MVW's announcement and the rate continued for months, and the TUG Marriott forum moderator,
@Dave M , went above and beyond as a go-between using his contacts to try to flesh out every single detail we supposed. If you notice the Marriott Points FAQ on TUG wasn't posted until three years after the DC implementation, and it took every bit of that time for the hundreds whose contributions are contained therein to collect info and share their experiences of actually using the DC.
All that to say, it's not a surprise at all that whatever integration they're intending to introduce to Vistana/Hyatt owners hasn't yet been introduced in the relatively short time they've been under the MVW umbrella.
I'm still in the camp that says the easiest way for MVW to move forward is to keep the Marriott, Vistana and Hyatt set-ups as they are, under the umbrella but separate (with the possibility of existing trusts being combined as much as is legally feasible,) allowing existing ownerships to enroll in the DC Exchange Company subject to a one-time fee and annual Club Dues for access to "internal" exchanges among all brands under the MVW umbrella, as well as, allowing automatic enrollment with new direct purchases from each company.
