No complaints; very organized. The guides were all very friendly and knowledgeable.The stops were very much on time

The tour was the perfect way to see the city, since I only had one full day. Because of the lighting parade the tour cut off short, but it gave me time to see everything.

We are Chicago Natives, but have wanted to take this trip for ages. We had an absolutely perfect day, slightly cool and sunny. Both of our tour guides were quite animated, entertaining and full of information. The tour hits all the major sites.

We chose this trip ahead of the big bus tour.Both similar stops and frequency.This one cheaper.Generally very good. Only 12 stops.It would be useful to get on and off in a different order - otherwise it takes ages to get to some stops.

Amazing tour of Chicago! Had a great tour guide and she was so helpful with making our trip complete!

We took the tour in the afternoon and we also did the nighttime tour. Both were great and I highly recommend them.

We loved the tour, its was very intresting and at the same time absolutely not boring, fun and easy, love it and highly recommend to everyone .

We purchased a 2 day package online prior to coming to Chicago. We used every bit of it!! Great drivers and very educated on the history and current Chicago. Thank you so much.

Other than the dolphin show, riding on the top of the Double Decker and seeing the city was my sons favorite part of Chicago! The buses were clean, the guides on the bus were super informative and it was a great perspective of the city, the pointed out so many cool things we wanted to stay an extra day just to check them out!
The only challenges were the ground crew were not very knowledgeable about the route or where to go and the bus tour itself takes (I was told) 2.5 hours min to make a loop so we had to hop off and walk to other stops a few times to make scheduled plans on time, plan accordingly.

Overall a great experience and will make sure to take a bus tour again!

Even though it says rain or shine it doesn't consider it also affects visibility and the open topped bus created a rain fall down the back stairs. Needless to say we chose not to go through with the tour.. The tour guide and driver were wonderful in helping but couldnt tell us if we could use our voucher another day. I called the number on my invoice which was not Viator but Chicago City Hop on Hop off and they told us we can use our voucher anytime. I was unable to find a number to call for Viator.
