I obviously don’t know who the author is, but if his occupation is Toirah Learning (as implied by “bein hazmanim” reference), then where did the minhag of taking vacations start? I understand that bein hazmanim in Gemorah referred to a need to go home and work the field.
Netziv was convinced by family and doctors to take a vacation on Lithuanian lakes. He ran away back home from boredom. Rav Salanter did go to the “waters”, but did not eat mehadrin on the way because he was using OPM (other people’s money). This would not apply if you earn your own money, of course.
