Well worth the money if you use it properly. Ferry tickets, open-top bus, and Macau Tower are all good value and we used the voucher for bottles of water at the latter. Definitely saved money compared to separate purchases. Also recommend the Hong Kong Sightseeing Pass.
Hong Kong, Hong Kong
Valuable cost saving when compared to purchasing separately. Look carefully for counter A8 in the arrivals hall, though. The Peak, sky100, and HopOn-HopOff Rickshaw bus are unmissable and the card is simply accepted at each. Also recommend the Macau Attractions Pass.
