The Ulusoy and Bosfor
Turizm companies operating
from Offices 127 and 129 at Istanbul's Büyük
Otogar (main bus terminal) run
buses from Istanbul to these destinations:
For domestic routes (within Turkey
only), you can reserve
your seat and/or purchase
your bus ticket online through Ulusoy's
English-language website.
For international routes, hold
your cursor over Customer Solution
Center on the left side of
the page, and select "International
Travel Routes" from the drop-down menu.
What I got was "Microsoft VBScript
runtime error '800a0411'" but maybe
you'll have better luck, or maybe they'll
fix the error.
