I've actually seen a show about "luxury" campgrounds that really do have concierge.
It was a show on the Travel channel. Folks pulled in with their $1M + RVs. Someone then took over and parked and hooked up the RV for them.
They can have gourmet meals brought to their RV. Have their laundry done for them. Have daily housekeeping on their RV. Arrange for tours, etc.
It really was amazing.
I also saw a show where a couple flew in on a private jet, had a limo take them to the RV resort where there RV was all set up for them, and they had wine and hors douvres (sp) waiting for them on the patio by sunset.
