Took the architecture boat tour on a Tuesday afternoon in August. Our cruise had a decent crowd, but there was plenty of space on board. It was a very clear day, which was great for the actual sightseeing, although we both got a bit of sun while sitting on the top deck of the boat. Our tour took us along parts of the Chicago River, where we saw quite a number of architectural highlights. Our tour guide, Patrick, really helped make the experience memorable, as he was very informative and also entertaining. Taking the cruise allowed us to see the city from a different perspective than usual, and we came away appreciating the history of the city even more.
