I've been staying at a few Marriott properties lately, and I have a few Marriott trips already booked for Europe, so I signed up for the Brilliant mainly for the platinum status. However, I am rethinking the value of the 650, or 350 after the res. credits are used. Just curious, if I cancel the card, would I lose the platinum status immediately? Anyone else find value in this card? Maybe I am missing something.
