I like this Hilton as it is near O'Hare and I can fly in and take free shuttle to hotel. With CTA train nearby, you don't really need to rent a car. The hotel is clean, modern, with nice size rooms and bathrooms. I have stayed in the Junior Suite and enjoy this room if you are going to have friends visiting you. As a Hilton Honors Gold member I received free full breakfast and high speed internet on my visit in March. The restaurant has never been very busy when I have eaten breakfast their(usually on a Sunday morning). Only caveat is when there is a large "family" type convention going on. I was on the 10th floor near pool and elevators and there was a constant stream of young people passing through the hall chattering and laughing so it was noisy most of day and until after 10pm at night. The Rosemont Hilton has a nice business center and I have used it each time I stay instead of bringing my personal laptop. Nice pool on 10th floor is also a plus.
