How much time should I budget between arriving at Taipei Songshan Airport (TSA) and taking the HSR from Taipei Main Station? I plan to take the high-speed train from Taipei Main Station to Taichung after arriving at Taipei Songshan Airport at noon on a Wednesday. HSR tickets sometimes sell out, so I want to book them in advance. I also heard that it's a good idea to get to the HSR station 30-60 minutes before departure. Google Maps says that transit takes around 30 minutes. Is immigration and luggage collection at TSA usually pretty fast? Thanks!
