When I checked into this Marriott tonight, the Platinum welcome card included with my key states: "Our Concierge Lounge is located on the 15th floor and is open Sunday evenings through Friday mornings each week. Please join us in 2 Rivers Grille on Saturday and Sunday mornings for your complimentary breakfast."
It is nice to see although I have no reason to be here on a weekend. It would be great if all Marriotts did that.
