we also did the wine festival..2010, we went in as strangers and ended the night as friends, 6 greek locals joined us 2, they spoke no English...we no Greek but we all understood each other within an hour..my husband was up doing his Anthony Quinn with a Greek lady of advanced years to Zorba!
By the end of the evening spent in great company with so much laughter she had written down her phone no 3 times and wanting us to come for tea tjhe next day, when unfortunately we had to fly home.
Amazing night promised for anyone who visits that time of year.
