I attended the event organised by Pablo M, at Geneva Polo Club last Saturday.
I found it to be a very relaxed and informal atmosphere, very child friendly and a great opportunity to spend some quality time outdoors with the kids watching a sport played at a reasonably high standard without the exhorbitant costs one normally associates with "polo".
My kids loved the day, (the pony rides on minature ponies (my two year old was even taller than one of the ponies), the live band, the match, the picnic, the dancing) etc, and the guests I brought along also had a great time.
Bar prices were reasonable, CHF 25 for a bottle of wine, CHF 5 for beer, and the Asado BBQ offered lots of choice.
Thanks to Pablo M for bringing this to my attention... I woudl certainly attend the next one.
The weather held out and we stayed from 430pm till 10.30 pm...
