If you are in for sightseeing tours this is your cheapest and most economical option. They combine a few tours together and push you to buy their all tour pass, I think that is not a great idea as Chicago has unpredictable weather. If you have time, go tour by tour. Main tour covers 12 destinations and if you really wish to get down and see all, you need a two day clear pass to achieve that. Tour ticket does bring in some incremental token freebies, they are OK, one can use them at least a few of them like Milk Chocolate at Hershey's. Free Garrets Popcorn is too small a packet to bother about. It is definitely a cheaper option than hiring a cab and moving around.
