We did both the daytime tour, and evening tour; the bus stops DEFINITELY need better signs indicating pickup stops; we were walking all over the museum area (stop #8) trying to find the pickup spot (we had gotten over to the museum area via the water taxi from navy pier); after waiting around about 35 minutes, in an area that appeared to be the spot on their map, we walked over to a worker inside a green trolley by the museum, and asked if he had any idea where the big bus picks up...he told us we were in the correct spot, he said it is not marked, you just have to "know" where to go....we waited about another 15 minutes, and finally gave up and took the water taxi back again over to Navy pier; it was extremely frustrating!!! Not to mention a huge waste of time! The day before, we got off the bus at Navy pier, about 6:05pm and were going to wait around for the evening tour bus….the bus worker gruffly said to those waiting around that there will be NO boarding for the night tour until at least 6:45pm (basically like a "go away" type thing).....we killed a little time walking around but went back to the bus area about 6:35pm, knowing it didn't leave until 7pm....and the bus was loaded already, not with the people from the daytime tour who had been told not to hang out waiting...they were selling tickets like crazy....and putting those people on quickly; we got on the bus about 6:40, and got some of the last seats....so much for "no one will be allowed to get on until at least 6:45"....not sure what happened to those who listened, and waiting to come back to the bus right before 7pm.... it would make a lot of sense to go the other direction also, not only have busses going one way; that was disappointing also
