Asia
Having lived in Asia for five years, I can conclusively say that it is an amazing area to visit whether traveling alone, with a partner, or with family. It’s home to some of the oldest cultures in the world, amazing foods unlike any you’ve ever tasted, and friendly people.
There’s no need to wait until they’re older to take your children to Asia. Most Asian countries are extremely family-friendly. Plus, luxury hotels in Asia are some of the best in the world.
That said, Asia is a big continent, and you could spend a lifetime exploring it. We tend to return to the same favorite spots over and over again.
