Hyatt Lisle
I stay here whenever I visit Chicago and the Sommerfield Suites is not available.
The hotel looks a little 'dated' in the lobby; but none the less is spacious and has an interesting fountain. There is a bar and restaurant -- which is nice, but nothing really to write home about.
The rooms are sharp and spacious. Each one has a small desk-like table in the middle that divides the sitting area from the bedroom. It has a TV on a swivel in the middle so you can watch it from either area.
The bathrooms are nice -- but have those annoying 'plastic toilet seats' that us girls could do without.
The staff is friendly and knowledgeable and in case it is needed -- there is a Wal-Mart near by (which happened to be great for me when I lost a phone charger).
If you are traveling with children who need something to do during the day, head out of the hotel parking lot and go away from the freeway on the main road. There is a huge, beautiful nature center that has lots of exotic plants and creatures. I have not personally been -- but have heard great things about the exhibits.
The downside: no free internet....not anywhere in the hotel. You can sign up for one of those BS T-mobile daily accounts and for $10 it's tacked on to your room.
