“Where would you take a tiyul to”
She could go on a 6 week tour of E”Y and tiyul to her hearts content, while saving her parents most of that 21k. If any of my children ever told me they wanted to go to E”Y for yeshiva or seminary and used “tiyul” as an argument, I would sign them up for a 6 week tour and enroll them in a local yeshiva/seminary.
