So this is my understanding:
The MVC Trust Owners Association voted to "add" 3% processing fee for Legacy Owners. This will begin in 2027. (I put those quotes there for a reason I will mention later.)
For Weeks owners it is more complicated.
The fact is if you are a weeks owner, your dues ALREADY factor in an estimate for processing fee - they make a reasonable assumption of the number of owners who will pay by credit card and calculate the fees, and spread it among all owners in the MF. It essentially becomes a line item in the Operating Budget.
But let me be clear: If you are a weeks owner, and have been been paying by CC, you ALREADY HAVE been paying some portion of a credit card swipe surcharge all these years. For that matter, all the check payers have also been paying said surcharge all these years, too...
MVC cannot just flip a switch and force the 3% to the payment portal for Weeks owners. It requires Resorts to adjust their MF accordingly
If you are a Weeks Owner who pays by CC, you already have a surcharge buried in your MF, so you might as well get some points out of it...
So if there IS a change at some point for Weeks owners, the result will be that a Weeks owner sees the full 3% when they swipe their card, and the Weeks owner who pays by check will not.
At that point, paying by a CC suddenly may become a negative proposition.
Early this year, Chase Sapphire Reserve still gave 4x for dues (February statement). This is after Chase changed to a highly restrictive travel award policy that excludes many forms of travel.
If Marriott portal changes and they send you through a third party site that does not code as "hotel", points suddenly become 1x...
This all being said, I think the OP outrage is very misplaced.
Remember how I said Weeks owners already have the surcharge baked into the MF?
Well, so do Legacy Owners.
Marriott said so: processing fees are currently "funded through the Association’s annual budget, which means they are shared by all Owners regardless of the payment method used.”
So what they are really doing by making this change is making the Credit Card payers eat the full 3% directly, and stop making the ACH payers eat anything. I am not a Marriott apologist by any means, and I was pretty damned concerned after reading the thread title and before researching. Thankfully, this is more of a nothingburger.
