I think what matters in travelling is not how far you go, how much money you spend, or how long is the trip.
Perhaps what more important is the companion, the traveller's mood, and if what you see/do is interesting/inspiring to you. A scenery can be very beautiful but if you see something similiar before, it might lose the impact on you. A meal can be good and expensive, but you might enjoy and remember an interesting street food more.. Getting lost isn't that bad after all when you end up discover something else... you might forget the histories and facts about the places you visited, but you never forget a funny/silly remark your friend make about places.
You can have a great trip even if it's a few days or a few hours.
