After a lifetime of traveling and working I took late retirement at 70 so I could travel like a rockstar. 73 countries so far won't die before the money runs out or the booze in business class. Try the Hemmingway Bar at the Grand Hyatt in Buenos Aires its free. Hyatt sent a car to pick us up at the airport. Went fly fishing in RIo Monso in Patagonia just up the road. Have fun.
I got scammed by a persistent taxi driver upon arrival at the airport.... way over charged me! Won't get caught like that again. Agree with you re checking beforehand and ensuring no one takes advantage of you. Enjoy!
