I will be traveling to Osan Air base in a few weeks. Since I am not military I have to take the regular Korean express bus instead of the military bus. Would it be quicker to take a cab? Is it safe to take a cab that far of a distance? I know it's expensive but I want the quickest, SAFEST and most direct route because it will be late at night when I arrive and I will have 2 large suitcases.
