Actually, looking at it from the staff's side: you might be two associates and it might be a gaffe to put you both in one bed. The best way the staff can handle it is to ask:
" I see you're booked for a king bed, is that all right with you?" [Hilton BKK].
It's elegant, not awkward and leaves ample opportunity to correct any mistake.
In Japan once, we had to run out the door after trying to check in. The owner just got out screaming with a broom and we ran.
