They don’t buy back at aulani, poly, copper creek or boulder ridge...and none of them have their resale values collapse. They may be lower than certain others, but there are reasons for that (poly’s
point chart is high, aulani is in Hawaii etc) The reason that the values hold is demand for the product...Particularly the rental demand. If rental demand died, resale prices would get crushed (ie go to zero). As long as there is a spread between dues and rental prices (particularly through rental brokers as that is easy) the timeshare will have value regardless of what Disney does (even riv resale has value due to the rental market although I’m a little skeptical of that holding as there could be issues in the future rental market if you don’t rent the points out immediately...due to everyone trading in but you not being able to trade out)
There are many other timeshare companies with rofr (Wyndham), that have values of essentially $0. All about the rental markets as a lot of people in Wyndham can’t rent for more than their dues...thus causing the value to disappear
