I think the root cause of all these issues is trying (or pretending?) to make the square peg “timeshare” fit the round hole of “flexibility.” This goes all the way back to the creation of floating weeks, and more recently the points systems. Quite simply, timesharing is a zero sum game where one owner’s “great trade” is another owner’s significant loss. Added to the mix are numerous publicly traded middle-men extracting their pound of flesh on every transaction, and hordes of lawyers administering the mountain of entities spun up to encapsulate the underlying ownerships.
Don’t get me wrong, I’ve done very well with my SPG/Vistana contracts, but I am well aware that my gain was someone else’s loss. TUGgers in general learn to get value from their ownerships by working the rules of the systems to their advantage, but we all know that if every owner did the same things we were doing, the house of cards would collapse.
At the end of the day, timesharing has become divorced from its original purpose: prepaid, predictable, cheap vacations for people willing and able to commit in advance. All this discussion of adjustments to booking windows, etc. to further disguise the product as something it can never be is just lipstick on the pig. I think the big timeshare companies know this too… but it gave them something to sell for the past 20 years, so it apparently fulfilled its purpose.
