Terrible experience! We were very much looking forward to this relaxing cruise after a red eye flight from the west coast...but we were unable to actually take it due to extremely poor information from the tour provider. Wrong address for the departure and wrong sailing time boat left an hour before we were told to be there! listed on the printer tour details combined to make the event a no-go for us. No one was in the kiosk on dock side to provide support front-line phone representative tried to help by offering us another sailing time but the supervisor behind the scenes who never took the time to actually come on the phone to talk to us was terribly inflexible and unable to work to offer a resolution/reservation that fit our schedule.
We have used Viator-curated tours in many cities in the US, Europe and Australia and know how to read the tour details and make it to departure points on time. This missed event was due to poor management and terrible customer service from what I would call a lackluster at best organization. Take my advice and spend your money elsewhere - Chicago has so many wonderful things to do other than this tour!
