Great hotel but big WiFi issues...
Stayed on one of the SPG floors in a very nice room... But the WiFi signal was very weak. Intermittent at times which was more frustrating than no signal. Tech support was not helpful and admitted that they have signal issues to the corner rooms, especially when the hotel is full and lots of people are using WiFi. 
As a business traveler this did not meet my needs and was very frustrating.
