We took a 40 minute architecture tour at 7:30, so it was after dark. There are quite a lot of stairs to get down to the dock from Michigan Ave, so be cognizant of that if you have bad knees. There might have been a ramp somewhere, but I didn't see one. The boat wasn't full, so there was plenty of room to spread out and social distance. Everyone wore masks. Below deck, there were restrooms and a fully stocked bar. Our tour guide, Josh, was great. Very knowledgeable. Make sure to bring cash to tip him! Would love to go back and do the longer tour during daylight sometime.
