Family vacation - fantastic hotel. Clean, modern room, excellent staff from service to desk staff.....can't say one negative thing about them. In fact, a number of staff went out of their way to help us with requests beyond what you'd normally expect. Location is super....the Omni is more or less in the center of the Magnificent Mile, and you can walk to most attractions or get easy transport access. Would recommend getting the GO Chicago Card that lets you get into attractions and skip some lines....if you plan on going to a number of attractions, you'll come out spending less than paying for each place separately. On some reviews people seemed really thrown by the check in desk being on the second floor.....not really any issue, though, jeez take the elevator one flight, no biggie. We requested a corner king suite and it was great, quiet and still had a nice window view of the Hancock Tower. The Grayline bus 'hop on / hop off' ticket is handy to get around to some of the attractions, and the only times we needed something else for transport was to go see Wrigley Field (took their Red Line train) and to go to Lincoln Zoo (hotel arranged a driver for us -- they have a hotel car that you can book in advance for transport to attractions). Great number of things to see in the city.....Navy Pier, Wrigley, Lincoln Zoo, the Shedd Acquarium, Oak. St. Beach if you want a wind down time, Hancock Tower, Sears Tower (now called Willis Tower), and even Water Tower Place (our little girl loved the Legoland store inside). The Hershey store was, well, what you'd expect.....and Ghirardellis as well. Food wise, loved trying some authentic Chicago Style Hot Dogs and the Deep Dish (go to Giordano's.....head and shoulders above the others). Ate at a few really good places along Rush Street (breakfast, dinner). The River tour is good for a slower pace. Millenium Park is great.....good food, the Bean is visually something to see, and our little girl loved playing in the outdoor water feature / water park they have there. If you're in town on a Saturday, catch the fireworks at Navy Pier, really well done production. Chicago itself....no real 'rough' areas that we saw, but we were on the Mile. It's a really big city, so night life is there and there's regular night time sirens going off, so bear that in mind when booking a room. Pretty much everyone we encountered was friendly, which was nice. I'd like to go back to Chicago and would not hesitate to stay at the Omni again, the level of service was really A+.
