In brief, she has had a terrible time of late and I can afford to take her to either.
She is worldly wise but not well travelled.
I know both well, and also used to work in SE Asia.
I suggested India (initially as DH and DS don't want to go so it's not somewhere I'd go with them) but a couple of mine and my friends mutual friends have suggested Thailand as it's 'easier' as an intro to Asia.
We'd be going for around 2 weeks, this time next year (give or take.)
My friend is 'open to suggestion' (but possibly doesn't quite know what the suggestions really entail - she basically wants to be looked after, which is absolutely fine, but also makes me wonder if India will be a bit hardcore.)
So, as I am a bit desensitised to potential culture shocks - what are the thoughts of others...?
