We love our electric golf cart.
Both of us have bad knees. Our cart enables us to move about freely and enjoy all the amenities of the campground/RV resort. The swimming pool, store and any activities are much easier and more convenient to us. We greet people as we pass and sometimes have very pleasant conversations with other campers. It's also much easier to carry chairs and cooler with snacks and beverages.
Essentially traveling with a cart gives us more bang for our buck. We perceive having and using a golf car based vehicle as value added to each camping trip.
There are many campgrounds that do permit carts but restrict usage of gas golf cars. Some petroleum types can be a little noisy, especially the 2 cycle models. I'll refrain from critiquing peoples actions and try to stay on topic and answer the OP.
