Once again its not a one size fits all answer. Getting additional power to individual sites in general will be most costly than a remote charging station.
However we know this is not always the case.
Parks will invest as demand increases. In most cases parks will decide which location will be most profitable.
Campers will adjust accordingly. a CG with at site charging will be more desirable than a CG with remote charging. (assuming there is a at site charge site available!)
CG's that provide EV charging will be more desirable than a CG with no EV charging allowed. Supply and demand will sort this out!
