We took the Signature tour only on the first day. Left at around 2 PM and we were back at 6 PM. Carla was our tour guide and she gave us a very good description of the various items as we went along the tour route. We were looking for a place on the top deck of the bus, it was jam packed, we had to be content sitting in the bottom deck of the bus. We just got 5 minutes to sit in the top deck after 5 PM, it was so cold and windy that we had to get down. For sitting on top, make sure you have good jacket. Among the freebies, we picked up only the T shirt and the Garret Pop Corn. We spent most of the time at Navy Pier, just walking around the food court. We had done the tour booking through Internet from India, much before the tour date and everything was perfect without any hickups. I would certainly recommend the tour to others, just make sure you start the tour during the early part of the day so that you get enough time to hop on and hop off at various points along the tour route. Make sure you get a place in the top deck, because that is where the fun is. You should look for Carla as your tour guide because she will keep you thoroughly engaged and entertained. She would involve everyone as they would get on to the top deck. Sh would sing songs for you. She is the highlight of the tour. We got only one day at Chicago for the tour, but I am sure the second and third days in the neighbourhood would also be as great as the local Signature sightseeing tour.
