I took this same tour a few years ago and liked it quite a bit, so it was a shame to see how far downhill they'd gone. And I was emarrassed that I had recommended it to my family and they all signed up for it at $28.00 per person. The bus was horrible - it was a very hot night and the air conditioner barely worked. It rattled so loudly when it was idling that we could barely hear the tour guide. Not that we missed much, mind you. The guy was not a good speaker at all, and not very knowledgeable, either. The sights and stories should have been very interesting, but he made them dull and boring, and we all couldn't wait for it to be over. Just a very poor experience all around, and made us end our otherwise wonderful family weekend in Chicago on a very sour note.
