Before Flying

Change Currency:  The Arcade in Raffles Place.
You can hardly find any Money Changer in Taiwan.  And most local banks do not have currency exchange services.  So always remember to change enough currency before you board the plane.  But in any case that you are so excited about the trip, that you totally forgot about the money issue… You can still find money changer at the airport, but the rate is definitely not as good as that from the Ah-neh uncles at The Arcade in Raffles Place.

With all these connectivities, you don’t really need to purchase any prepaid 3G phonecard, unless you are those who has the habit of updating your whereabouts instantaneously.  Com’on, you are suppose to be on leave, it is the best time to play ‘invisible’ and 與世隔絕 and enjoy your holidays!
