My sympathies.

I've never booked non-refundable hotel stays in the USA as, for one thing, the discounts weren't that good. I did in Spain pre-covid as the savings were quite significant. Had two nights stayed at two different spots, one a pension and the other a large hotel chain. We were unable to travel due to Covid.

Both the pension and the potel offered us future credits. Probably only due to worldwide Covid.

I agree with the posters...research higher-ups @ Marriott (e.g. Elliott.org).
