Is it cheaper to get the airport express travel pass for my planned itinerary:

If you want to take the airport express train from the airport to the hotel, the cheaper way for you is to buy an airport express travel pass with one Airport Express single journey. You can use the pass for 3 consecutive days of unlimited travel on MTR (except Airport Express, East Rail Line First Class, Lo Wu and Lok Ma Chau stations). Well, when going to Ocean Park, you need to take bus and you need to pay for the bus fare.
