What to plan for best Chicago trip?

I am pondering to be a part of chicago bus tour. I will surely get a nice kind of experience by taking tour like this with my mates. I want to know from you that what will be the best travel option to pick and how many days will be enough to collect lots of funfilled memories?

Well, I read your post I am sure your plan is too good. I am a travel freak and it is my crush. Last month I have enjoyed this tour. This was an admirable tour for me. So, I suggest you have booked 4-Day Chicago to Indianapolis, Chattanooga, Nashville and Great Smoky Mountains Sightseeing Tour. I am sure you like my suggestion. All the best for your trip. I want to say that in your trip you must enjoy photography there. All the best for your trip.
