On the day we took the tour, we took the first bus available at the Water Tower around 11 am. For whatever reason, they said the “night” tour wasn’t available that day and rides stop at 5. That didn’t work with what we had planned very well. I wanted to stop at Riverwalk and take the boat tour, get back on and stop at Millennium Park. After the boat tour, we didn’t have time to stop at anything else.
Also, the app wasn’t working at all and the busses aren’t as frequent as what they state. It just made it more stressful for me than what it should have been. I would recommend the tour but as others have said, the narration is really cheesy. But, the kids loved riding on the top and looking around the city. It’s also great if it’s your first time there. I hope they fix these kinks. It would be 5 stars if they did.
