1) swimming pool is included in the membership fees. there are a few other things that do not require additional fees, can't remember what they are, though. gym and classes are extra. the classes are "farmed out" to other companies to provide.
2) there is a pass for the ferry. it used to be for 50 trips, but i am not sure if that is still the case. there is no monthly pass ANYWHERE in hk for any form of transport. there IS a thing called an OCTOPUS CARD. you purchase them at MTR stations but they are good on all bus routes, at mcd's, at the supermarkets, at 7-11s and various other places around the city. you just top them up when they run out of value.
