I'm going to Chicago in November for a conference. Out of all the conference rate hotels, I have narrowed it down to the Westin Chicago River North, Hyatt Regency Chicago, or InterContinental Chicago. I'll probably be bringing my significant other.

From Tripadvisor, it seems that the Westin is nicer. However I only have Gold status with SPG, but I have Diamond at Hyatt and Platinum with PC. Which hotel should I go for?
