Buenos Aires just didn’t click for us in our first few days. It was just too big a city, with lots of homeless people and police everywhere. So we took the buquebus, a high speed ferry, to Montevideo in Uruguay. This is not a cheap way to travel as it cost $688.35CAD for all of five of us. They had half of the boat dedicated to duty free sales in USD. Some good deals but none that we could partake as you had to buy 3 or 4 items to make it worthwhile. It was a great destination and lots of fun.
