Sorry to hear about your mom.
We've owned for 21 years, since back when it was Fairfield. I can't remember hearing of Fairfield/Wyndham making an exception when an owner missed their end of use year date. Of course it's possible that it could have happened and I or others didn't hear about it. However I think that's a policy set in stone.
It would be great if Wyndham had a few specialist VCs, Vacation Counselors, specifically trained to help/advise family members who have to take over management of the account. I'm sure that happens more than most of us realize. If one of them wasn't available when you called you could leave a message with the days and hopefully several hour time frames you'd be available for them to call back. They would give you a crash course in what you needed to know. With instructions to "write this down." The first thing would most definitely be to know the use year dates and the options for any unused points.
Back when I was struggling to learn the system, before the webite became available, overall the VCs used to be much better trained. There was a man named Edwin who was a wonderful and desperately needed help for me. He would have me call on Sunday mornings because that's when things tend to be slow for them. He would have me write things down, highlight important things in the directory, repeat back to him what I learned so he knew I grasped it. When the website became available all we had was an older computer that our then teenaged son used. When we got a new computer our neighbor took me in hand and taught me so much. One day when I called in to book something, not a Sunday morning, I randomly happened to get Edwin at a time they weren't busy. He walked my not very willing self through getting on the website and doing basic searches.
Somepeople can read things like the directory once or twice and they've got it. A TUG member and former Wyndham owner
@ron p. is like that. Our son excels at that. He for sure didn't get that from me lol! However once I spent sometime using the website, everything just gelled for me. I needed the hands on, learn by doing.
If your mom doesn't have a directory, call in and they'll send you one. In the meantime if you go to the bottom of the Wyndham websites you'll see Publications in the dark blue section at the bottom. Click on it and you'll find the directory.
At the top of the website you'll see the 3 white lines next to "CLUB WYNDHAM " on dark blue background. Click on the lined and you'll see "Owner Guide". Read through "Resources" and "The New Owner Quick Start."
You don't have to log in to access either the directory or the Owner Guide sections. In no time at all you might know more than your mom ever did in all the years she's owned. We've seen, and some of us have met, a lot of older, long time owners who really don't know much about the system, what they own, etc.
