For us Wi-Fi at an RV park is a must, even if we did have to pay an extra fee for it. Today almost everyone travels with a laptop or some kind of device that you can access the internet from. We haven't been to a RV Park that charges for Wi-Fi. Before RV Parks were offering Wi-Fi most parks would have a computer in their front office where you could connect to the internet. I like having Wi-Fi access.
Now I don't need to leave the comfort of my coach to get online.
