Although you didn't ask, the Contemporary has at least one room in "Tower Club" on the 12th floor that is accessible. Last time I stayed on 12 they were gutting the room to set it up.
Note that 12 is "semi-concierge". It is staffed from very early in the morning until about 4:00pm for normal concierge assistance. They have continental breakfast available, as well as light snacks (such as cookies, etc) and beverages through the afternoon. Rather than a formal lounge the area near the elvators is where the desk and tables and chairs are.
The 14th floor is "full concierge" and is staffed until about 11:00. Their lounge is the size of two normal rooms, complete with giant TV and during the evening they have snacks and desserts. Therer is also an honor bar as well as wine available.
On both floors the rooms do have refrigerators, and they will keep them stocked with a few botles of water and a few cans of juices and soda, usually of your choice of flavors. (For example, ours stayed stocked with apple juice, diet Coke, and diet Ginger Ale.)
