Importance of WiFi and other tech while traveling?

Our over the winter trip taught us many things, and one of them is that park WiFi is a joke. Verizon hotspot and a 16gb data plan does it for us.

Now, if you could replace the park system with a multi-point cellular system, you might have something. I think most RVers would pay an extra buck or 2 a day for decent internet. If you could get enough throughput to replace the park cable TV (another joke), that would be stellar.
