In analyzing the comments in this thread, there seem to be two primary categories:
1) those that have a lot of points and use a lot of guest confirmations for others
2) those that may or may not have a lot of points but only use guest confirmations for others occasionally, if at all.
The OP and I seem to be in a third category, which is those with aging parents with a lot of points who cannot travel but, in my mother's case, hope to do so once their health improves. We (and I realize the OP's mother passed away ... my sincere condolences ... so she is no longer in the same situation) aren't looking to use GCs for others routinely, but just temporarily until normal usage resumes.
When I joined the Navy, the recruiting slogan was "In the defense of our nation, there can be no second best." The same goes for defending aging parents.
Would I litigate pro bono if Wyndham does something to my mother? Absolutely, like a [insert appropriate expletive here] pit bull. Would it be worth the time I put into it? Perhaps not, but I would certainly put up enough of a fight that it would be very expensive to defend.
But again, I'm looking for help on how to navigate what appears to be a clouded path without poking the bear.
