We have an 8,5 hour stopover in Taipei in July, arriving at 3pm and flying out around 11.30. We are really keen to leave the airport and have a bit of a look around, but we really want to be back with loads of time to spare (by around 8pm) and we are not confident to venture out without a guide. We also don't want to clear customs and find that we can't get a driver, who would need to be able to speak English. How easy is it to find a driver who speaks English on our arrival at that time in the afternoon (I am imagining around 4pm by the time we clear customs)? Thanks in advance.
