can I suggest El retiro polo club in Argentina? I went there for a course in March and will pop back in this week as I'm spending Christmas in Buenos Aires. Email the owner marcos LLambias on elretiropolo@yahoo.com I had a great time there, learnt loads and it's quite reasonably priced.
How are you doing? I suggest you also to come to Argentina! I have a travel agency with focus on polo trips, since in march here in Argentina is going to be the Argentina Polo Tour I think is going to be the best place to be, Im also taking polo lessons and I can reccomend you some polo ranches depending on your polo experience and what are you looking for ...
please send me an email to amuntrips@gmail.com and I´ll help you the most with your polo trip!
