My ds and his gf are in their 20s, have everything the need etc, so for Xmas I want to gift them a few days away in Amsterdam (they both really want to go).
What's the best way to do this? Vouchers limits them to the provider I choose, in fact do holiday companies with vouchers even exist anymore? Cash might get used up on bills and general life stuff, I don't want to book it because this will be their first holiday together and I want them to have all the fun of choosing and planning.
Any ideas?
