The hotel made a bad mistake but it seems to be owning up the whole way. Here's another data point.. when I had a bad stay at the Columbus Airport Mariott, the GM agreed to cover me under the Ultimate Reservation Guarantee, which was the room, plus $200, plus 2 free room night certs. They were not able to get the certs, so they gave me 45k points instead which I accepted. Being comped Platinum seems a little out of the ordinary, but I think paying nothing for the room/valet along with 40-50k points, and maybe a little bit of cash would be appropriate. Please note at Courtyard the Ultimate Reservation guarantee is a lot less (only $100, 2 free room nights only for Plat) so keep that in mind too.
