请问什么是travel insurance，怎么办理呢，急急！
去NTU的NIE（National Institute of Education）读teaching chinese的diploma，学校给了个邮件如是说：
you are advised to purchase your own travel insurance for the period from Aug to Dec 2012 as during this period, you are not covered under any medical/hospitalisation insurance.
请问这个travel insurance有必要办吗，应该如何办理呢？
易学政
旅行保险
网上就可以在线买，像Aviva这样的。
楼下说国内也可以买，你可以比较比较价格和保单内容。
