Great trip! Lots of fun. My thanks to all the alumni in Taipei that made the convention work.
Travel back out to the airport was just as easy. Another 140$ ( US $ 3.50) I’d recommend that Evergreen bus big time. Taxis were also fairly cheap in Taipei. If the bus wasn’t such a deal. Subways were also a good deal at about US$ .60-1.5 depending on distance.
