In town for conference.
On a recent trip to Chicago, we found that the hotels blocked for the American College of Surgeons were already booked. I turned to Kayak to find other accomidations near the Miracle Mile. The Doubletree was in the right location for the meetings and for shopping and nightlife without having to get a taxi. The hotel was clean and the staff friendly. 
The concierges were very helpful. Taxi's are not as plentiful in the evening as they once were, so they came in handy in getting a car at the time we needed for the airport and when we went away from the city. 
The value was the big perk in this reservation. We were already spending a lot of money, so at over a thousand dollar savings for this hotel vs. the block that the ACS had, made it perfect!
