Great Price. Friendly and Helpful Staff. Terrific Views of the Harbour. We had a great time meeting and chatting to a family down from Queensland who sitting nearby. I would def do it again and recommend it.
Good if you are not in a hurry. Would take at least days to get around the four of them, Especially if you hop off to do stuff. But if you only have one day, then I get the green bus that drives past all the major attractions. All in all, I would recommend it.
