Thanks OverRated for your encouragement, I have now booked us a week in Chicago and I am finalising a rental at Bridgeport (through VRBO) which I have been assured by the owner is only 20 mins drive to downtown even in rush hour, not that I have decided to drive yet. I don't want to bombard him with more questions (already done that in the last two days) but I really need to know (from experience)what driving is like in Chicago. I have thought about taking cabs if necessary but we are 5 in total so if the cabs are like over here, they will only carry 4 people. Also I am considering taking my niece with us making 6 of us so driving will be more convenient. I have been told that parking can also be a nightmare in terms of cost and finding a place downtown but saying that, someone else said its not as bad as London . Also if I do end up hiring a car, is it advisable to book through a travel agent or directly. sorry for the lengthy thread, just so much I need to know . Almost forgot, what is there for us to see and do minus the shopping for me.
