Personally NO Beach Bum,
The food in the Greek tavernas, restaurants and bars is sooo good that there's no need for me to take anything.
Crikey if you're only away for a fortnight, it's not as though you're going to miss something so much that you can't wait until you get back home to get it (and I'm sure it'll taste even better then because you've missed it so much)
When in Greece I rarely eat much in my apartment anyway (although I do take sauce, salt and pepper sachets when going to some other countries, for picnics etc).
I realise that many folks do take tea bags etc, but seeing as I never drink tea I never have to worry about that!
