That’s a bit presumptive, is it not, booking.com and maker of this challenge? Let’s not assume everyone wants to (or has the ability to) have kids, shall we?
Let’s say instead I was taking any young person somewhere (whether or not they were related to me). I would definitely take them out of their home country/environment. I like both the Emirates and Singapore to be ‘lite’ versions of their regions (Middle East-lite and Asia-lite). These locations are non-intimidating ways to share a new culture without scaring off a young traveler by completely throwing them into the deep end. Knowing the Emirates better, I think a 5 day trip in Dubai/Abu Dhabi would be a fun place to explore.
