I would agree with HKTraveller... to a point. It is definately not worth the extra cost for SuperClass. And at that time, after your long flight--- you'll most likely just fall asleep for the ride. So go with the regular fare and I don't imagine it will be packed on the ride over. As for $$ change into HK$ at an ATM at the airport, the taxi's & everything else in Macau will take them at the same rate as their currency (you just can't use Macau currency in HK).
