Interesting choices Bath. I think without kids, I'd probably choose Vietnam or China as I love Asia and would enjoy living somewhere totally different culturally. But with a family I would say Dubai or Singapore, as I think they are more family friendly and safer (in terms of health predominantly) and my preference would be Dubai for the following reasons:
- I've been to Singapore
- More financial gain
- More culturally different (I would think but I haven't been there LOL)
- DH has been there on work trips and enjoyed it.
