I'll try to give you some sense of relief as requested. The reality is this. The points buckets have existed within the back office systems for a long time now. These points buckets simply haven't been exposed to the front office website. So the good news is that most the core functionalities for the points buckets - those are a known quantity and changes to the back office systems shouldn't be necessary - or somewhat minimal when compared to the front office changes. The bad news is that the logic for processing resale reservations separately likely either didn't exist or must be changed as a result of the recently announced changes. That said, the overall the changes to how the reservation components work isn't rocket science. As long as the logic is programmed correctly - making net new reservations after mid-August when these changes are moved into production - I expect we'll see some bugs as always - but it should work for the majority of use cases from the outset. That said, I'd expect Wyndham TUG owners to fair worse than most normal owners - since many Wyndham TUG owner accounts - especially those who fall into the commercial rental business bucket - are far from normal accounts and are outliers by definition. Expect problems if you have millions of points, hundreds of transactions, dozens or hundreds of GC/HK/RT activities. Just one man's opinion.
The bigger change that I'd be more concerned about is the points adjustments based upon account audits that have been announced. Essentially they are doing an account audit for the current use year for all impacted VIP owners and performing changes to points buckets and GC/HK/RT counts retroactively best estimate. I tend to agree with the consensus - take screenshots of your account information the day before the changes are rolled out. This is the area where I'd expect the most heartache.
