I live about 1 1/2 - 2 hours southwest of Chicago. No plans today, so I was thinking of going up, and hopefully getting my iphone replaced. (The ringer / vibrate button broke off) It looks like the Orland Park, and possibly Schaumburg locations would be the quickest for me to get into. (Don't really want to go all the way downtown) Anyone familiar with these locations? is there one that you think would be better to go to over the other? Or any suggestions of which one would be best to go to today? Also, do I just make an appointment with the genius bar online, before I take off, to make things go quicker??
