Forgot to mention secret word at checkin at the Monaco Denver as it was a long travel day and it was late. Did receive a good IC welcome benefit as per my preferences but only a $10 minibar credit when I mentioned it at checkout, the rep told me that I need to do it at checkin or they have little latitude. I find this to be at the very least inconsistent as I have done this a few times at checkout over the last year at other properties and have been given at least a $25 credit for parking or restaurant charge.
