Better Choices than this Hotel
I stayed here for a conference in March, next time I will stay elsewhere (such as the W) and just take a taxi to the conference.
This hotel is a typical large, busy conference hotel. It is also a bit out of the way with no stores or shops close by or places to run out and get a bit to eat. 
I stayed on the concierge level which was not worth the extra money. The morning breakfast and evening appetizers were not good at all. Your better off going downstairs to the cafe and getting a bagel. Also the rooms are typical, again not more than a basic conference hotel.
