Hi all
I finally did this trip today and decided to just get on the TSA-TPE bus, TPE isn't the quickest so I am glad I did this.
I seem to have misremembered that I could pay for the bus with a credit card. Not the case so I had to switch up 1000 YEN for it and now have about 170 Taiwanese dollars for my first beer when I come for a proper visit.
Bus was exactly 50 mins. Plus another 20 mins wandering aimlessly around TPE looking for the check in counters. Didn't see much traffic at all
Thanks all for your help
