No nothing special.....just make sure you have enough life jackets for all people onboard to go though the locks. (They must be worn while inside) Dont letgo of the wall ropes inside the locks till the "OK" horn is blasted. And the river is mostly No Wake through the city. Oh and the only other thing to watch out for is just after the Wacker St bridge on the left hand side is a fountain/waterfall type thing. On the top of every hour it shoots a stream of water across the whole river for 10min. If you dont want to get wet dont be under it!
