Buenos Aires to Montevideo
I will be in Buenos Aires for next year in summer (winter for S. Hemisphere) 2010. I would like to spend a couple days in Montevideo since it is so close. Is it worth flying from EZE to Montevideo? If so, which airlines fly there, and how long does the flight take (economy or business)? If there are other options, are they reliable or efficient, or even worth using other methods than flying?
