I ran into great difficulty booking a tour for 108 people due to the fact that almost every company I contacted wanted payment in advance. This was problematic from the perspective of a lack of recourse if the guides failed to show (which I’ve had happen before). Trip Advisor doesn’t make researching for large groups the easiest, but I finally took a chance and called their highest rated tour company for Chicago. I’m glad I did!
Mr. O’connell was incredibly accommodating, and he and his fellow guides did a fantastic job of helping our bus drivers navigate the city while offering trivia (with gift cards as prizes), Chicago style popcorn, and a wide-array of historical knowledge of the city ranging from the humorous to the macabre. They arrived on time and made sure that we saw the sights from the bus as well as from the ground. If I travel with another group to Chicago in the future, there’s no doubt which company I will use!
