I love the word "glamping". Some brag using the word. Some tease about the bragging that other people do about glamping. Still either way - it is the perfect word.
*googles the word "Glamping" * What the F.
Why do they even bother
I think it depends on what you mean by "glamping".
For some, having a camper, fifth wheel, something you tow, is "glamping", whether it be a $5k thing or a $1M luxury RV or bus.
For others, "glamping" is camping in a cabin or tent-walled cabin, with beds and such.
Heck, our YMCA has family camping trips at a YMCA camp - food is included, but you can choose a cabin, a tent cabin, or bring your own tent.
I have a sister with a camper. She and her husband and dogs camp a LOT in it and to me, it's luxurious. Then again it felt luxurious to me when I upgraded to a cot. I'm too old to sleep on the ground.
ETA: campers and such give you more flexibility. You can camp when it's colder, so have a greater range of use.
