Bad from beginning to end. The location is probably the worst I've seen. It's in a boat harbor where you have to go around/get out of the way of boats, kayaks, paddle boards and other jet skis in this small area. The water was very choppy (4-5 foot waves) the day of our reservation so no tandem riders. Which is what 2 couples wanted, but they refused to give a refund. 4 of 5 agreed to ride solo. My daughter, her boyfriend, my nephew and myself. They refused to let us go out together for the safety of the jet skis. Said there was a greater risk we would damage their equipment if the 4 of us went out together. I had to go with my nephew for 30 minutes and after we returned, they let my daughter and her boyfriend go out. It's not like we were a bunch of drunk teenagers, I'm almost 60 years old and my nephew is 36. I told the manager that we were paying for the experience/fun of riding together as a family. He said that they had to protect their equipment due to the weather. The worst part was it was a very busy Saturday so you had to watch out for boats coming and going. The waves were really high and the boats causing a wake made it even worse. Once you get out of the harbor area it's wide open, but again there are still boats coming and going. NOT FUN AT ALL

We had a blast kayaking and sup at 31st street Harbor. The prices were half that of North Ave Beach. We had a blast.

My boyfriend and I had so much fun! Employees were very laid-back and relaxed while still giving enough instruction and safety information. We had the whole harbor to ourselves! The water was beautiful and warm, and the jet skis were great quality. Would highly recommend.

Chicago Water Sport Rentals was a great vendor to work with when renting jet skis. Their staff was extremely personable and provided great customer service as they walked us through the rental process. They were thorough and did an excellent job explaining everything we would need to know. Prices are a bit steep, but overall worth the cost to interact with good staff.

Chicago Water sports is an awesome place to rent a waverunner! They are fast with customer service and work with you if you are running late. I will be going back next year more often.
