My friends and I flew to Taiwan a few weeks ago. Honestly, travelling to Taipei is probably one of the most challenging trips I had, as I wasn't able to research well given a very hectic schedule at work. Also, I haven't read a lot of extensive posts about Taiwan so I'll try my best to make my posts 5-Day Taiwan trip as detailed as possible. Kindly note that I don't speak any Chinese language so my tips may not be applicable to those who can speak Chinese.
Here's a few things you need to remember when you visit Taiwan:
1. Purchase an EasyCard
EasyCard is Taiwan's all-around reloadable card that you can use to pay for all types of transportation (MRT, buses, Maokong Gondola, U-Bikes), for convenience store purchases (7-Eleven, FamilyMart, etc), Starbucks Coffee, other fastfood establishments and many more. Note that you get 20% discount on fares when you use an EasyCard for transportation.
You can get an EasyCard for a deposit on 100 NT (Php 146), which is refundable when you return your EasyCard.
2. If you're between 15 to 30 years old, get a Youth Travel Card.
Taiwan Youth Travel Card is a membership/discount card to different establishments around Taiwan. You can get yours at any Visitor Center or Tourist Center, just don't forget to show your passport. Here's a list of establishments where you can get discount using your Youth Travel Card.
