SET OFF is a narrative form best suited for stories and epic tales - not this context.
We correctly set off ON a trip, set off FOR a destination. So saying “set off for a trip” sounds incorrect.
Also, SET OFF only refers to the point when the person leaves for a destination - it has no place in the context of this post.
