Friends got the satellite internet last year...make sure to check as they had a data limit. I'm sure they could buy more data but it was pricey.
Really, a cell hotspot with unlimited data plan is about the best combination of lots of data at reasonable price.
We also will download youtube videos for later watching when the campground has decent wifi for use when we will be in more remote areas. Even though they throttle the data on the unlimited plans after a certain limit, they do still retain the right to cancel your service if your data usage get excessive. This helps keep it under control as video is really the biggest consumer of data by far.
