We're giving Greece a go this year after years of going to the Algarve. We always found that we needed to bring light jackets etc, because the evenings could be very cool- you'd need a blanket or shawl to sit out on the terrace most evenings, once the breeze picked up.
Does anyone know if this is the case in Kephalonia? I don't want to waste the space on all those extra clothes if they're not necessary. We're off to Sami, btw.
