Hi I am planning a tour to argentina in December. I plan on doing 4 days buenos aires, 3 days ushuiah. I plan on doing mar del plata. It looks like a very nice city. I've done research on it. Would anyone recommend 2 days or 3 days. If you have been there please let me know. Or if you have any recommendations for mar del plata.

I would suggest sticking to the Playa Grande area and going before Xmas. After that date it will be crowded with vacationing locals. Have a great time in my country.
