We are locked into RCI Points. After downsizing, the only timeshare we have left is a 1BR (resale) triennial points unit in Las Vegas. If we want to exchange, we glom 2-3 years' worth of points together & use those to reserve a week in somebody else's timeshare somewhere else (Florida, usually).
More commonly, we use our RCI Points membership to snag bargain
Last Call reservations & occasionally low-cost
Extra Vacation Getaway reservations when they go on sale.
The reason that works OK for us is that our favorite timeshare vacation spot (Orlando-Kissimmee FL) is overbuilt with timeshares. Plus, our favorite timeshare vacation weeks (early January) are off-season for that part of the country. Ideally, it works out to luxury timeshare vacation accommodations at Motel 6 & Super 8 rates.
So far, so good.
