Holland
As one of the most compact, lived-in and traffic-free capitals of Europe, Amsterdam is built on a scale that works well for kids.
The Saturday-morning farmers' gathering in the Jordaan, the New Metropolis science museum and Anne Frank's house can all be followed by a visit to a crafty little toy shop called Bell Tree and supper at the Pancake Bakery. Then there's a Puppet Theatre held on Dam Square on Wednesday afternoons, bikes for hire and museums and galleries galore.
But the biggest Dutch treat is the Kinderkookkafe, where children prepare and cook the food, serve drinks from the bar, wait on tables and present you with a bill at the end (book in advance on 0031 20 625 3257). Two nights in a two-star hotel with Amsterdam Travel Service (01992 456056) costs £199pp with flights, with longer holidays and self-drive/Eurostar combinations also available.
Middle East
