it depends on where you go and what you play.

Ocean Park $25, Disney $255, Wax Museum ticket $12 yuan, accommodation $3, cable car (round trip $4.), Star Ferry $2.5, East Rail $33, Watsons mineral water 6-7$HKD, and dinner? 5。 The fare for the jet flight to Macau is 145 Hong Kong dollars.

I suggest you travel freely, and provide you with a route guide for your free travel for reference:
