Parking is directly in front of each building. The only time one might encounter a "long walk" is if they are in a corner unit and parked at the opposite corner of the lot. But even then it's all relative.
OKW has parking outside each building but the buildings are smaller and so are the lots. In some cases you may be parking in the lot next to your building or across the street because your lot is full.
NOTE: I did notice Congress Park tends to have larger landscaped courtyards at the entrances so that can add a bit more distance between te lots and units.
