I have no idea if the OP, Sapper, owns Marriott timeshares or not but s/he posts knowledgeably as an owner on the TUG Hyatt forum. The first post about this supposed new thing being offered to Hyatt owners was put in the TUG Hyatt forum
here, and then cross-posted to the TUG Marriott forum
here (because speculation has been swirling about all kinds of things since Hyatt and Vistana came under the Marriott umbrella.)
You seem to want to denigrate Marriott in every way possible but you continuously confuse the fact that the Marriott timeshare company is completely separate from the Marriott hotel company, you confuse where this "Marriott Beyond" thing was introduced on the TUG boards, you confuse whatever this "Marriott Beyond" timeshare thing might turn out to be with what the "Beyond Barriers" hotel thing is ...
I get how the Marriott timeshare products aren't everybody's cup of tea. I get how the Vistana and Hyatt timeshare people want to keep their identity despite their companies being acquired by the Marriott timeshare company. I get that you hate that SPG has been absorbed into Marriott's Bonvoy by the Marriott hotel company. (And believe me, Marriott Rewards people aren't all that thrilled with the new name either!)
But like I said before, I don't get deliberately misrepresenting or completely discounting what the Marriott timeshare owners are saying that might help you come out of the fog of confusion. Everybody needs a villain, I guess, and obviously "Marriott" is yours.
