I always specify that one King bed, even booking directly in web pages or with TA, and with TA I make them very clear, a must.
When we arrived to hotels, (happened a lot in India) they where surprises that out TA booked a King bed instead of 2 beds, we always answer, that was or request. and simply you receive a smile.
Never happened to us something weird, even in Nepal with sex is a seriously Tabu.
