The above applies to Marriott owners/members using purchased Abound Trust Points and/or Abound Exchange Points from enrolled/elected Marriott Weeks. I would guess that
if the website interface for Vistana owners/members is the same as for Marriott owners/members, which I gather it's at least very similar from what I read here, then similar rules should be in play and the same or similar links should be available to you. Whether they are or not, though, I would say that the best way you all can learn your basics is through experience using Abound, the same way we Marriott people had to learn. Don't take for granted that the rules we live by are the same for you.
[ETA] What is it, an hour later and I just learned that the info in the FAQ is outdated because Marriott is disabling some links. GRRRRRRRR. Check out
this post for the working directions.
