Funny thread.
IMO, I equate the folks that have to go to the $80/night KOAs or whatever every night with the same folks who will spend $250 at the Marriot for a king suite and dont' blink an eye at $50/person for dinner and drinks on a normal Tuesday night...
It's all relative. We stay at an expensive RV park when necessary or preferential due to the proximity of other activities and we stay somewhere that is $0-30/night the rest of time, because even though we've become glampers (in my book), I'm not looking for the manicured lawn doggy doodoo stations and complimentary happy hours at the clubhouse type of places.
Complaining about the price of campsites, or luxury RV sites, more appropriately, is like complaining about the cost of anything else....it's just complaining.
