Many good points in this thread.

I will say that my company uses TravelPerk, and I contacted them about this. They said that they definitely have an agreement with Marriott and that my status should be honoured.

However, the clerk at the front desk told me that I "booked via booking.com", so it sounds like maybe TravelPerk ....ed up here and booked through a separate OTA (like someone mentioned above). They offered to book a separate hotel for me and have the current one completely refunded. But I'm already in the room and I really don't want to move (it's still a good hotel, just disappointed that I don't get my usual perks). So I'll keep talking to TravelPerk about how they'll "make this right" as they stated they would.

I really wish I could change the title of this thread to "TravelPerk not passing on my status w/ Marriott".
