I'm taking a short vacation in northern Taiwan around January 1 and I want to travel about 90 minutes away from Taipei the weekend before New Years. I've had some difficulty reserving the train tickets I want online for the express trains. I can reserve some trains on the days I'm traveling, just not the exact ones that I want.
I've also observed that hotels are all nearly booked up (I have already made reservations).
However, I understand that I can always get on a local train without a reservation. How busy are the local trains from Taipei to Yilan and back the weekend before New Years? I can stand for 1-2 hours if I have to; I will have a large backpack as luggage, though. Thanks.
