It is a travel log of a sort but that's because most people in 1962 did not get to see much of the world outside of the US so they actually enjoyed the scenery. It was refreshing to see a movie where two people actually attempt to be discreet in front of other people about their possible sexual activity. Not even considering morality, it just shows a little taste. That part may be considered old-fashioned by some, but the problem Prudence is wrestling with is one relevant today. She does want to be a grown, sensual adult but she doesn't want to go down the road that will lead to cynicism. How can you be sure how far to commit yourself, because if you make too many wrong choices, it really does become like "shaking hands" and what fun is that?
