Chicago Gents - A Question About Locations

I'm sure this has been asked to death on this board, but I have a question about which locations you gentlemen find most convenient for incalls.

I'm travelling there in March with my partner, and we're considering a few options.

So far, we're torn between:

* downtown
* near O'Hare
* Oakbrook

Do you find any one of these to be more convenient than the others, or is there someplace else we should also be considering?

I fully admit that I'm not overly familiar with Chicago and area, so I'd appreciate any help you're willing to give.

Thanks in advance,

Morgan
