Having said that, as TUGgers know, you can get some great values with weeks-based trading - we traded a lowly Silver HHI Barony Beach Club Gardenview week to get a September 2017 week at HHI Grande Ocean (Gold season). We placed the request in early April 2016 and gave II a wide possible travel window from mid-Sept through the end of October 2017, but we didn't get a match (a mid-September week) until late November right after Thanksgiving. Having said that, booking the same reservation at Grande Ocean with points would have required 3450-4000 points (depending on view category), so that equates to a maintenance fee cost of roughly $1,825 to $2,100. Our maintenance fee cost on the 2017 Barony week was only $1,351 (and that was inflated by the $75 Hurricane Matthew special assessment). So it was a good financial deal to trade this time instead of using Points, and we may play the weeks trading game from time-to-time, but I am very glad we own both an enrolled week and Points, so we have the option to use either system. I can't imagine being forced to revert back to weeks based trading for EVERY trip we want to take. That's why we sold a non-Marriott week we used to own that traded in RCI, and bought into the Marriott system in 2014. I detest the waiting and uncertainty of trading. While Points come with no assurances either, it's much closer to "what you see is what you get."
As far as the rental approach is concerned, I guess I don't have the patience for that either, and based on the OP's comments, I wonder if they would have the same concern. I'm also not enamored with the person-to-person rental market, either acting as a renter or as a landlord. My one experience with trying to rent something on Redweek was not positive, so that does taint my perspective a bit. We had to cancel a summer 2016 trip to Maui, so before canceling the reservation and getting the Points back, we first tried to rent the week on Redweek. We priced it in line with the other summer 2BR OF Maui Ocean Club weeks, waited about 3 or 4 months, and only got one nibble from someone looking to see if we would cut the price significantly. About 90 days before the date of the booking, I gave up and canceled the ad and called Marriott and had the points refunded to our account. We then used those points freed up from the one week Maui trip to book 14 nights at other MVC locations in 2016 and 2017.
