As I understand it, the main difference (other than price of course), between these two types of rooms is that the lounge in the Sugar Loaf Bldg. does not serve liquor in the evening, or at all for that matter. I am staying in the main bldg RPC, my brother wanted to stay there the same week but there is nothing available. The CM on the phone suggested Sugar Loaf; he thinks he might rather stay at the Poly (concierge). The price for either is virtually the same - $42 more for the Poly. Are there any other differences between the RPC and the Sugar Loaf bldg that he should take into consideration?
