I don't know what not travling for work has to do with using points at all. I've never used points for work travel, and I bet a lot of other people never have too. Points are usually used for personal trips, and you haven't said that you are unable or uninterested in ever doing any personal travel again.

And if you do personal travel, someday you'll find yourself going someplace where the even Fairfield Inns are expensive on dollars but are not booked up and so can be gotten on a low number of points. It's for occasions like that that I never want to get rid of my points, but hold on to them for when I can get a better value (than right away).

So I don't understand the need to burn. Perhaps (if this is your actual concern) you should instead be asking how you can keep them alive a long time without work travel...

Meanwhile, the only way to get good value from hotel points is to use them for hotel stays (at times and in locations where the hotel is low-priced on points but high-priced on real money). Second best may be to transfer to an airline where you'll get good value from them. All redemptions for non-hotels non-airlines involve Marriott paying for merchandise, and so all will at the same lousy rate.
