“Weird portmanteau,” thought I. Then I thought of family “camping” vacations from my childhood (1950s). I suppose those were pretty “glamp.” *heh*
The seven (or nine, of my paternal grandparents were along, as in one of the camping trips) of us would pile in a station wagon, packed to the roof–and beyond!–with people and possessions/supplies–and pulling a trailer built by my grandfather, full of large canvas tent, campstove, lanterns, fuel, sleeping bags, food, tools and other supplies to last seven (or nine) people for a couple of weeks.
Grandmother handled most (no, all–she wasn’t much of a sharer in the kitchen, inside or out) if she were along. Otherwise, mother did most of the cooking with one or more of us kids helping. The white gas Coleman stove was used for most cooking, but when the camp stove was not needed, cooking was sometimes over a real camp fire. Either my dad or grandfather directed camp setup and teardown/packing. Fishing poles and tackle boxes (where use was allowed) were always along.
Well, that was “glamping” for my family in the 50s. *shrugs* Seemed pretty luxurious at the time, and I suppose it still is.
