Unfortunately, times are changing rapidly. Whether we like it or not, the expectations for Internet access are not what they were, even just a few years ago. High speed broadband access is widely available. The ability to stream and download large amounts of data is looked at as completely normal. Music, Movies, TV, etc., etc., etc.... I can't remember the last time I turned on a radio or played a CD!
Campgrounds remain woefully behind this curve. We can hem & haw about the reasons, the costs or whatever, but at some point the situation needs to change. YES, it may drive up the cost of staying in a private campground and certainly there will be as many folks angry over it as there are elated!
To reject change will only serve to get you run-over when it happens, which is inevitable. We spend 7 - 8 months in our rig. I want broadband access with no limits. I'll be perfectly willing to pay for the service. Campgrounds need to move into the 21st century and make it happen.
