I may be incredibly old-fashioned and out-of-date but what's wrong with "real" nappies???
A dozen terry nappies takes up less space in your suitcase than a dozen disposable ones, it takes a couple of minutes to wash them through in the morning and drying them is a cinch because, unlike the UK, you actually get sun in Corfu.
Worked fine for me when we took 2 little ones in nappies away to Corfu all those years ago when disposable nappies were still a new-fangled invention which had not even reached parts of England, never mind Corfu!
OK – the downside is that you spend a few minutes of your holiday washing nappies, (although probably LESS time than you would spend hunting around supermarkets for more supplies of disposable ones) - but the upside is that you save a fortune on disposable ones, the only thing you have to buy is a small pack of washing powder which is available very cheaply at any of the local supermarkets.
And before you say anything Eileen – Yes, I know I'm a dinosaur!
