Thanks
@SueDonJ et al lots of good information to digest. From a quick glance comparing an enrolled week (since that is what Vistana/Hyatt will probably be offered):
Enrollment: MVC DC = $2375 (but can be waived/grandfathered. Opt-in); HGVC = $599 mandatory for all new properties (Dev & resale)
Annual Dues (basic): MVC DC $195 (includes II fee); HGVC = $159 (includes RCI fee)
Reservations: MVC DC = free; HGVC $65
Borrow Points: MVC DC = Free; HGVC = Free
Save Points: MVC DC = Free; HGVC = $109
SKIM MVC DC = 1 night ; HGVC = None
Lock-off Fee: MVC DC = Free ; HGVC = n/a (points based system)
Exchange Program: MVC DC = Free II ; HGVC = Free (internal system)
(within system)
(Marriott preference);
Exchange Program MVC Legacy = $189?/exchange (II); HGVC $239/exchange + Fixed Points (RCI) + resort fees.
(external)
It would take 27 reservations in HGVC to break even with the enrollment fee difference. If one makes 2 reservations a year that is almost 14 years or 9 years if you make 3 a year. Of course a waiver improves the break even. The annual dues are in the ballpark with each other. This does not factor in the other fees such as skim. I am a newbie so perhaps I did not get this right.
I am too new to Vistana to do a similar comparison. Perhaps someone more knowledgeable could take a crack at this.
