My husband called in December (about 18th) to the Points number; he was told they were going out that day.
I called again on Thursday, 1/8, after we got the proxies (because I thought those were the maintenance fee bills) -- I called PAHIO VIP number in Princeville. She said they were to go out in the next few days. I said that I so distrusted Wyndham that I was concerned this was a technique by them to put us in default so they could take our weeks. She said, "Oh no, you will have 30 days from the billing date." I still would not put it past Wyndham to print them on 12/18, and mail them on 1/18 with an indication that they are due 30 days from the billing date, i.e. 12/18.
We don't own at KBV, but at Pahio, Shearwater, and Makai Club Cottages, but I suspect they are all being handled in a similar fashion.
