If you're going on a once-in-a-lifetime opportunity like this then why waste the time doing internet stuff that you can do for the rest of your life.

Use the opportunity wisely. Soak up the new experiences. DOn't be one of those fools that travel halfway around the world to sit in a McDonalds or an internet cafe.

Forget about the internet, email, wikipedia etc.They'll all still be there when you're done.
