It's 14 days including flights. I won't know his itinerary until he gets back from SP cruise Wednesday week but I see him often enough at home as he lives in the next street.
I've booked a holiday but not a cruise. Sth Korea in September.
My son and friends leave for SP on Ovation tomorrow.
He will also be on a Japan/S Korea cruise at the same time as me.
I didn't notice Turkish pistacchios when I've been in Turkey. I did like their walnuts and dried apricots which we bought from roadside vendors. A walnut wrapped in an apricot was a great travelling snack.
I eat a lot of nuts, mainly Macadamias, pistacchios and cashews, usually from Coles. The macadamias seem to taste better, to me, than those from Aldi or Woolworths.
