My take. park Wi-Fi is a variable. Where I'm at is one of the best Park Wi-Fi's I have seen and still.. It strugles to keep up with demand.
And folks who buy Rouku's or other streaming devices.. DO NOT HELP ONE BIT.
Most parks it sucks even if you are the only user!!!! though some parks
Well one park I know of has at least 3 Cable accounts, the fastest possible speed and it is STILL not enough, even with nanny gates so not all devices connect it's not enough...
So do not rely on it.. Many parks (Public parks, city, county, state, federal) do not have any.
