We booked our 4 night stay here for a conference next door. As it became close to our arrival I was nervous after reading reviews that I would be unhappy. In particular because we were not close to town. What we discovered was much different.
The room itself was great. The bed was enormously comfortable and we did not find noise to be a problem (we were on 9th foor).
We asked James, one of the concierges where we could run and he gave us excellent directions to the Lake Front. Just down the street to the bridge on 18th street over the tracks and to the lake fron via Soldier's Field. We walked back from down town as well as enjoying several runs. The lake front is beautiful, felt very safe and had lots of "people traffic." No scary "bad neighborhoods."
The main restaurant needs a major over haul, The people were freindly and service was great but the room was stark, hard and the lights too bright. The bar, on the other hand was very comforatble and well laid out. The prices for all food was very high but there is not a lot of choice yet in the area. We did happen on a Society Bistro a few blocks away that had the BEST coffee and muffins (for less than we paid for 2 coffees at the hotel). Near the museums.
We were very happy with our stay - all personnel were friendly & helpful .

Stayed at the Hyatt last night to attend a Bears game and the proximity to Soldier Field is perfect (we walked there). The hotel itself was very nice and exactly what I expected. Our room and bed was comfortable (although they were unable to fulfill our request for a King bed and we ended up with 2 queens). Paid $100 on Hotwire for the room and it was quite nice for what we paid.

The hotel was beautiful, the beds were very comfortable, and the double sink was very nice. However, the walls were very thin and we got in trouble for being too loud. The only other bad thing is the location, so far away from where we wanted to go. The free shuttle service only takes you to a few locations, but it doesn't bring you back. And it only goes one time at every hour. Make sure you check your bill. I got charged for movies I didn't watch. I would recommend this hotel for business use but not for vacation with friends.

I stayed at the Hyatt McCormick Place for two nights at a convention in August 2007. Paid $169 a night for the 'business plan' - I don't think it was worth the extra $20 for breakfast at the restaurant. The rooms are standard Hyatt, decent bed and sheets, but nothing fancy. No room safe and $10 a day for high speed internet. $24 a day for parking. The public areas were bright, airy, and clean and seemed to handle our group well. Not so for the one line coffee stand and the one restaurant for breakfast. There are no other options close to McCormick Place, so the food there is the only game in town, unless you want to drive or take a cab elsewhere. The guest floor hall on my floor was dirty and was not cleaned during my stay. All in all, fine for the purpose but I would not go back for any other reason.
