I've done Big Bus tours in Paris, Berlin, and Barcelona so I booked a trip while here in Hong Kong. I must say that unlike my other Big Bus rides this one left me quite disappointed. For starters, on the Kowloon side of the tour there's not one interesting bit of audio commentary. All you hear about is how you can find an expensive and inexpensive meal on the streets and similar banal points. Next issue was the interminable waits. I waited 45 minutes for the bus outside the Tin Hau Temple and then once on the bus we had to wait almost as long as we got to the main starting point at TST. So when you combine the lack of interesting commentary and the waits there's really not much value on the Kowloon side. On the Hong Kong side we had issue again with waiting for a bus as we finally gave up after 45 minutes at the Causeway Bay stop. Perhaps some of this was due to the New Year, but if so, they should not be selling full price tickets during this time.
