Welcome to FT! We look forward to your input, and hope we can provide input to you as well! And given your willingness to participate, I have a feeling that your hotel is run quite well/has the attitude we're all looking for when we stay at Marriotts.
We may be cranky at times, but you'll find that overall most of us love Marriott & we do praise as well. I've written 2 letters recently to GMs of hotels I've stayed at complimenting them on their staff, service, attitude & I cc'd the 'big guy' so he'd know how great those properties are.
Cheers.
