Yes, it Is definitely the Marriott Marquis next to the convention center. I ended up canceling that residence inn reservation and booked 2 rooms at the Marriott from the 18th-22nd for $350 per night plus taxes. I am looking for room mates for my reservation which they gave me a complimentary upgrade to a large corner room with 1 king bed and a pull out couch. The other reservation was split up into 3 one day reservations for the 18th, 19th, and 20th. Someone already claimed the 18th and 20th, but the room for the 19th is still available. It is just a standard room with 1 king bed.
