Remember that many parts of
the world use a different voltage system. This means that you'll need
adapters for anything you plan to plug into the wall, including your
laptop.
Well-prepared
If you plan on doing a lot of
work in your room pack an extension cord so you can use the laptop from
your preferred spot, regardless of where the outlet is located.
On your country
Arrange to have some local
currency before you leave as this will enable you to take care of your
first small expenses (taxi fare, refreshments etc) without having to
worry about getting local currency.
international health
insurance
Medical insurance is essential
when traveling. Medical treatment can be very expensive for foreigners.
Announce yourself
Never arrive at an office
unannounced. It is bad business practice and you may find the person you
want to meet is in another city.
