1. Airport Express Travel Pass:
a. Just for clarification, the website saysI get 72hrs + til the end of the lady day. So if arrive on Day 1 and use the AE to get to my hotel, and then don't use the MTR untill morning of Day 2, I get until the end of Day 5, nearly 4 days of use?
b. Also, I can pretty much only use it on trains, no buses (in HK or Kowloon), not star ferry? Looks like I need to spend $120 to break even. I'll probably go out to Lantau once and will probably take a trip to Tin Shui Wai. Then maybe a couple trips around town so it should be enough to break even just about.
c. Can I order it online and pick it up at the airport when I arrive? The website seems to say otherwise but that doesnt seem to make sense for something designed for tourists.

2. Is there a good website for looking up fares across all the HK public transit services (mtr, buses, ferry)? Like google maps directions but with fare info.
