Fair point, I don't know their motives, which probably vary from employee to employee.
It does seem to me that they prioritized guests who would be due refunds from MVCI above guests who wouldn't, but that could be a coincidence and not profit maximizing.
I never said they were within their rights to do so, and if it had been me affected I might have litigated the matter, not sure. But I'm not accusing them of doing anything illegal either, I don't know. But it certainly does seem to me that it's unethical to cancel a reservation for available space to accomodate someone else. Your opinion may vary, and obviously does.
I doubt very much that MVCI cares what I think. Their treatment of their customers has made me less likely to buy a Marriott timeshare, but I would only have done so resale, so it's no loss to them.
I'm very doubtful the motivation was the refund risk. Regardless of motivation, they prioritized for those who were reserved directly with Marriott in some way and away from II. I know many are looking at the fact that many of those exchangers were Marriott members also and most of those had likely used their Marriott weeks as deposits taking the stance they should be treated as owners in that instance, a position I don't personally agree with. I don't assume that companies are bad and only make decisions based on profit and I don't believe "the customer is always right" philosophy.
I do think they care what you are or I think but I doubt the opinion of an individual is going to affect bigger picture decisions in this type of situation.
I wonder what everyone's opinion would be if they had only left out exchangers that weren't Marriott owners, mine would be exactly the same. Obviously they didn't have the volume available to draw the line in that way. Did II refund exchange fees or just give replacement weeks? Even if they refunded fees they would still get the $$$ back when a new exchange was made so their only real cost was the time and aggravation dealing with it so I don't give them the high road in this situation. The real loser would be other II members. I don't know the Vistana system well enough to know how it's set up but I know DVC is set up such that the members would simply vie for available inventory if a resort were out of commission but not permanently closed, this is written into the POS.
I'd be willing to bet they looked at the resorts and units available and the volume of each group and the only single group that would allow the problem to be solved was the II exchange group. I'd be further willing to bet the only way to solve the problem by affecting only a single group was to cross resort lines. Then there's the volume of people they would have to contact in addition to all the other logistics. Maybe they took the easy way out, one that would also force II to do some of the leg work and take much of the heat. Whether this was the motivation or intentional, or even played into their thinking is hard to say, but it's what happened regardless of motivation and intent.
Regardless it was a mess for everyone and I feel for those who were affected. BTW, I also own on HHI both several Marriott weeks (GO, SW) and a condo in an OF resort.
