Hey Kylie,
I've just come back from a few days at my parents. I use Natures Babies eco disposables and eco disposable nappy sacks (otherwise there's no point in using eco disposables as the nappy will degrade but the bag its in won't!) when I'm away - Natures Babies products are available in Boots, Mothercare, Co-op and Sainsburys.
Life is too short when you are on holiday in my book! And boy am I glad - DD pooed big smelly poos (very unusual!) twice on the train home, and I'm so so glad I didn't have to take the soiled nappies back to my seat in my wet bag and stink out the carriage!
