You are right,
SixString. If you are traveling for serious work, and pushing hard all day long on the road, you do need peaceful down time.
Nowdays, our son is the one who does most of the really hard travel for our company and he always has his own room on the road (unless his girlfriend, who also works for us, joins him on the road).
Hunki and I, who have worked together for 22 years and still do some hard travel, always share a room.
All the rest of the "work" travel in our company is really mostly for fun.
