It was very well organized and the staff were polite and friendly. The tour was just great and well timed to enjoy the experience!
Other than the Viator voucher not saying which company the tour was with, the tour itself was fantastic. Totally worth the money, especially the cheaper kids' fare. I lived in Chicago for 12 years a long time ago and it was great to show my three young kids the fantastic views from the water.
Great tour! About 30-40 minutes but even with it being 85 degrees outside the lake was very cold. Bring an extra layer to enjoy. Other than that great tour ride, views are amazing and staff very helpful.
