MY EDIT: the OP was talking about WiFi and data providers in the same sentence. WiFi and MiFi are two different sources of data, but the rest of my post is probably still pertinent.
I don’t think it’s realistic to expect to stream Netflix or most other such media via wifi simply because most wifi is not tied to a T1 or better network. It is just too expensive for parks to deliver that bandwidth.
Even in a high end park that I winter in and that had half a T1 line, they could not handle the bandwidth degradation with just a few movie streamers. They we paying $800 a month just to deliver that and had a stroke about delivering a full line for $1700 a month. Bandwidth costs.
In most parks, they have already discovered they have to throttle users and cut them off when they catch them abusing the system. You are going to see that more and more unless they start factoring that kind of service into their camping rates.
Cellular networks are already taxed to the max and frankly, I think Netflix promoting their downstreaming over anything but a fiber optic or other high speed infrastructure is irresponsible marketing. They are creating a demand that cannot be met currently in the private sector by anything but the DSL or cable services, certainly no cell carriers.
Now if the desired effect is to drive up revenue for unwitting customers on the cell networks with overages, they have that going on in spades.
The huge demand on the cellular infrastructure from the explosion of smart phones and similar devices will continue to outstrip the carriers’ ability to deliver for some time. There will never be enough bandwidth for a demand that grows exponentially. It’s been that way almost since day one.
Cheap bandwidth is like cheap gas – those days are gone.
