All three of my children took time off to travel the world between School and University; taking anything from one to nearly three years.
None of them needed to write home for money, each working their own ways around as they went.
Of course it wasn't all work. Youngest son (sporting his beloved dreads, above) probably experienced more that the other two, but that was because he was prepared to do things on the cheap, in discomfort, and with a bunch of like-minded friends. The two older children were more discerning.
Above shows him in Oz about to wrangle with a Crock'. It's a good thing there was a fence between them.
With the world's current problems, our children will probably be staying home for their gap years; and, sadly, they will be lesser people for it. Another unmentioned aspect of the pandemic.
