I would say that's more than enough. We are going in 10 days and will be taking £800 with us for the two weeks for two people. We're going s/c and will probably have breakfast and most lunches in the apartment but will be eating out and drinking lots in the evenings. We usually bring some back too.
If we were at home we'd never spend that much in two weeks going out for meals every night and the odd bits of food shopping that we will need to buy.
I won't be buying many souveniers this year though, mainly because we've got everything from previous trips to
icmeler but also because of the weight restrictions.
