Anyone (Argentinians?) know of any unfussy, not expensive, kids polo camps? My boys ride (not brilliantly, just started jumps) & play hockey and they'd love to play polo. But it's so expensive in the UK! I'd like to send them to Argentina, ideally in or near Buenos Aires, to do a (sleepover) polo kids camp - like the French UCPA 'colonies de vacances'. Any recommendations welcome, thanks.
