easiest way to tour around the major attractions in hong kong! excellent job!
We took the Big Bus red single route (Hong Kong Island). It gives you a good overview of the most touristy parts. I wouldn't recommend to start the tour at 4pm, as the traffic makes it in large parts annoying, the bus is moving very slowly and you'll be breathing its and other busses diesel exhausts all the time. Under these conditions the tour ended around 6:30 and for this duration wasn't informative enough, you could see more by walking and taking public transport. The background music is terrible and should urgently be changed!
We bought the premium package here in HK which is about $50 USD per person or around $400 HKD at the time. I think it is a bit pricey considering that you can't immensely cover all the 3 routes. Realistically speaking, you might get only 50% of what it totally offers considering the 24 hour time limit. I'd you can save a lot by doing it all by yourself and just pick the attractions you want to see for the day. I also find riding the top of the bus a little bit risky for young children as the seats didn't have any safety belts.
Excellent service by big bus. Love it.. recommended
I opine buying the day big bus tour package (minus the night tour) is sufficient, provided that you have enough time to cover all 3 routes. Certainly, it is the fastest way (and maybe the best way as well) to get to know Hong Kong.
