Depends somewhat on your itinerary and destination, and your attitude.
For example, if you're going to a vacation at a lake, "Secret at Mystic Lake" might be exciting...but it's about crime at the lake, so that foreboding might not be so good for your stay there.
If you're traveling across the Great Plains, "Strangers on a Train" might upgrade potential tedium.
