The Open is played at the polo fields in Las Canitas (Libertador y Dorrego) - across from the race track. There is an entrance on Libertador.
You *should* be able to buy tix at the game tomorrow, the first weekend doesn't usually sell out. Not sure on the price for individual game - probably 35 pesos for the cheap tix (Dorrego Central) for the games this weekend (prices go up during the tournament). The tix is for both games on that day. Usually individual tix for the semis are around 80 and the final is 150.
