I'll be in Taiwan for a first time (weekend trip 1st weekend in March). will be arriving Friday night and departing Sunday night.

Browsing related threads I came up with the following:

Arrival: use bus and train to Taipei railway station, walk to the hotel (Sheraton Grand). Total travel time ~1.5 hours

Saturday:
Day tour to Taroko Gorge
Taipei Night tour (Dinner, Lung Shan Temple, Hwahsi Night Market, Taipei 101)

Sunday:
Taipei day tour (8.30am) (Presidential Building, Chiang Kai-Shek Memorial Hall, Martyrs' Shrine, Traditional Taiwanese Temple (have no idea what that is), National Palace Museum, Handicraft Center)

17:00 departure from Taipei station to the airport on high speed rail (train 867 departure 17:00 arrival 17:21) - I assume it is sufficient time for 20:00 flight?

I understand I can explore Taipei on my own, the only reason I am taking tours is supposedly save some time and the need to research where exactly to go and how.

Any comments will be greatly appreciated.
