Long thread but somewhat far I haven't seen what my family do, which is to take the other side of the trade. You can buy weeks on Redweek from timeshare owners (not outright, just a week in one year) and get a decent deal on vacation accommodation. Once you do it once the owners will often do a direct transaction at lower cost next year to avoid Redweek fees. We've stayed in many timeshares and been happy with the price/performance ratio.
I guess my feeling is that, at least for many years, I haven't been sufficiently in need for a too good to be true bargain that I wanted to get anywhere near opportunities like this. Probably a case of risk aversion to some degree. I have very rarely used AirBnB either.
