Yes.....This is going to cost the RV parks more if they want to offer cable or sat TV. It's not unlike the integration of internet into campgrounds. Some have terrible internet and some upgrade their systems to "just like at home" performance. It's expensive.
Yes, rates will have to go up, but so does everything else. I understand the pleas from campgrounds and that they're not all getting rich. With that said, have you tried to get reservations lately at a popular park....very difficult. The baby boomers are out and spending their money. If you want mine, you better spend it on your park or I won't be back.
Lastly, the addition of these last generation cable boxes are very difficult to integrate into newer coaches where the TV's are hard to access and use HDMI connections. It's like going backward in technology. We have DirecTV as our primary TV source, then campground cable and if there is nothing, we watch movies.
Side Note: We have a DirecTv DVR in our motor home and when they offer free movies, I record the ones I like. For those who may not be aware, you can watch the saved movies on your DVR even when you don't get satellite.
