I spend $75 to $100 USD a day and live extremely well. In addition, I did not know when I asked the question and see it mentioned above - blue rate of exchange means the unofficial or black market rate for dollar exchange that some places pay at around 7 pesos for each dollar. Some people may be adverse to breaking the law. I am using the official rate and not the blue rate to provide my answer in case you are tempted to use dangerous exchange sources. I found a legal way to exchange my dollars that will not suit everyone via my property agent in Montevideo.
