Naperville is not a locale that comes up on the radar very often and is a little more spread out than Oakbrook. Aside from some of the lovelies you mention OakBrook happens to be a bit more central to the rest of the suburban scene. Depending on the timing, you are more likely to catch a number of visiting pros that frequent the area. It also has a higher concentration of hotels, shopping, etc.and I think that goes into why ladies like OakBrook. I am sure there are plenty of NVille providers and many post in the BP and CL rags. Be careful, there are lots of scams and LE activity has been reported in recent months.

It helps if you provide info on the type of lady you are seeking.
