Hi,
My sister is taking DS1 and DS2 to Eurodisney in late february, with a friend and her friends DD.
Do I have to do anything to enable her to take DSs out of the country, particulary as they have different surnames? If me and DH write her a letter giving her permission, would that be enough, or is there something official I have to do?
This is the first time they've gone anywhere without me, and I'm a bit nervous anyway - so, I really don't want to have to worry that immigration/customs will whisk them away 'cos they think DSis is kidnapping them!
