The CR offer's two levels of concierge service. The 14th floor has only 5 standard concierge rooms and 11 suites. The lounge is open from 7am-10pm and serves beer, wine and cordials in the evening. I don't think the 12th floor has an actual lounge. I believe the food and drinks are set up on tables and you can bring them back to your room. The staff is available to assist you during the same hours, but the food service ends earlier and they don't have the beer, wine and cordials available. If you were looking for something comparable to the Poly, then it would be the 14th floor. If it's available, I would absolutely give it a try. If only the 12th floor had availability, I'd stick with the Poly, or perhaps look at some of the other deluxes.
