Was in Kos during Euro 2004, was immense, in a bar in Kos town when England got knocked out by Portugal. we'd spent **** loads so the barman invited us back the next night to watch Greece play France, needless to say my Raki hangover the next day has not been forgotten.
Went back to the same bar for the Greece semi-final too but we were flying back early next day so I had to be a little restrained.
Nice island hired a car for a couple of days and went and saw more of the less accessible locations, including the nudist beach on the south of the island!!
