When you buy travel insurance you can choose from two types of policies - Single Trip or Annual Trip coverage.
Single Trip Travel Insurance covers you for a single trip that originates and ends in Hong Kong.
Annual Travel Insurance covers you for all trips starting and ending in Hong Kong. You should consider buying Annual Travel Insurance if you travel frequently (more than 10 times a year). You will enjoy significant savings, and you won’t have to worry about purchasing travel insurance each time you travel as you are automatically covered for the entire year.
