I've been a Wyndham owner since 2007. I bought resale for $100. (A friend called me from Las Vegas once. He and his wife went on a tour from Vacation Village. To make a long story short, he told me the second offer they gave him for $12,000 wasn't bad. While he was talking, I looked it up on ebay. Same package, same resort, selling for $3. Yes, three dollars.).
Yeah, the certificate is worthless. I complained to Wyndham and they gave me points instead.
They generally let me out pretty fast. I tell them I'm 70, single, only have a few years more I'll be able to travel, and the points I have now (49,000 per year, believe it or not) work out fine for me. Makes no sense for me to pay $20,000 to amortize in maybe 10 years, plus the extra MF. Although one time a sales weasel told me that if I bought more points, I wouldn't have to pay any MF. And then there was the one that told me unless I bought more points, the MF on my 49K points would be $7,000 in a couple of years.
