Golf, like most things in HKG is expensive but as an S/O you'll be flying Ultra Longhaul only which means you work say 12 days a month, so you bid for Compact rosters and do say 2 x ULH trips back to back then 10 days off, on your days off you go to Thailand or the Phillipines which are covered with Golf courses and also very cheap: i.e:
Tkt.................$980HKG = USD $124
Hotac.............$240HKG = USD $ 30
Golf................$450HKG = USD $ 57
Food, booze etc.............still cheap and you get to see the world and have a nice time, also places like Vietnam are now opening up with golf courses and nice Hotels...........all these places have one huge advantage......they are CHEAP
