It seems that your Courtyard stay was for just 1 night. If so, and if it were me, I would contact the GM and be sure that he understands the inconveniece that you suffered - but also that he understands that the valet manager did go to great lenghts to right the wrong. (sure, it was incompetence that caused the situation, but give credit where credit is due to the mgr/staff that did fix things in the end)
Irregardless, I would hope that your valet was comped, if not your entire folio! I would ask for 50k points & to be comped to Platinum. If you can get a cert for a free night too, go for it.
That story is worse than anything I have ever encountered!
