Oh god, tell me about LAX. Being unfamiliar with its layout, I arrived there earlier this year and looked for an Information Desk. There was one, but it was unstaffed. Then I looked for a map. No map. Then I looked for someone to ask. Nobody to ask. I looked for signs. No useful signs. It was only when I was finally able to find a map online, not an easy feat given their awful WiFi service, that I was able to figure out where to go. WTF, LAX?
By the way, there is a shuttle train running between the two terminals at TPE.
