My reading of your phrase is a recognition that two different people could follow the exact same trip route, but come back to tell about completely different travel experiences. The way in which a person approaches a trip, the expectations s/he brings to the adventure, the unexpected happenings along the way - all these variables impact the overall impression and memory. Some travelers thrive on taking trips with minimal advance planning so they can be spontaneous and take advantage of whatever opportunities present themselves. Others want to meticulously plan every detail in advance so there are no surprises while they are on the road. Both approaches are valid; it all comes down to the type of travel experience you want to gain from your trip.
