Hi, I am going to Taiwai with 3 other friends on 24th September until 30th.
My initial itinerary is as below, (please suggest coz some days is still empty)

Day 1: reach Tao Yuan around 3pm. Planning to rent any cheap hostel nearby since leaving to Qing Jing Nong Chang next day.
Night activity: Shih Lin market since Xi Men Ding closed on Monday.
Day 2: Already booked accommodation at Shangri-la at Qing Jing (清境) but dunno how to travel from Taipei to that place yet. :S (please recommend. I'll email the hotel and ask them tomorrow)
Basically nothing to do there, just enjoy scenery and escape city life in KL.
Day3: breakfast n go Tai Chung city after visiting the free Swiss garden tour. Not yet book accommodation here too. (please suggest. Budget rm100/person) with clean private washroom. Don't mind separated)

Day 4: travel Back to Taipei or mayb straight to JiuFen and stay a night there. Suggest way to travel there please? From the previous post I read, got highspeed rail from Taichung to Taipei right? Would wanna try this.
If stay at JiuFen, what is there to do?
Day 5: Visit 101 tower and eat lUnch there at Din Tai Feng.
