OK if your type of campervanning is that you are 5 days here, 6 days there, 4 days somewhere else, and then return home. But if that was our type of holiday, we would have bought a caravan, not a campervan.
We are ‘travellers’, have a rough idea of an itinirary, but just love the flexibility of a day here, a day there, have a long drive, have a short drive, have no drive, do a hike, stay longer than expected when we like it somewhere, or move on as quickly as possible if a place or the weather turns out to be horrible, etc, etc.
The growing inflexibility of campsites is a hinder, then.
