We really enjoyed the Doubletree in Alsip, Illinois. There was plenty of free parking and they have some good "Park and Fly" deals for anyone flying out of Midway and taking their airport shuttle. The hotel was clean, beautiful and well-maintained. My little boy, who normally is mostly interested in the pool and the elevator, kept saying "this is really pretty" when we walked through the lobby area.
All the staff we met were friendly and helpful. The pool area was very nice, and offers longer hours of availability than some other hotels.The exercise area had quite a selection of equipment. It is worthwhile to get a room package that includes the breakfast, which is in the hotel's restaurant.
We would definitely stay here again when we are in this area. The hotel is in a quiet area of the suburbs, so the only drawback would be if someone didn't have a vehicle, there isn't really anything like shopping, restaurants etc. in walking distance. (We did have a good pizza and salad delivered to the room though.)
