Check the coverage map for whoever you go with - we have a mifi (Verizon Jetpack) and a lot of the campgrounds we stay in are pretty remote and either don't have any cell service or it is quite poor. We do have a cell booster which helps out when we are down to poor quality 4G or 3G but if you are out in 1X land, pretty much nothing can improve to stream much of anything - particularly not video.

Since we almost always stay in county or state parks (occasionally NFS or national parks) there is never a camp-provided internet. You can go up on a site like rvparkreviews and look through the reviews of various sites and generally someone will mention what the status of the park's internet is or whether they were able to get signal via their phones/hotspot.

Take a look at what the streaming requirements of the homeschool website are, they'll tell you what the minimums required are.
