Banning advertisements to kids is the correct approach. I've observed with my own kids, they genuinely don't yet have the mental faculties to be critical of advertisements. They see something advertised, they want it, simple as that. Their brains aren't developed enough for content with advertising nor product placement.
Maybe there's a sweet spot in limiting it to toy ads and ads for other content on the same platform that they're watching. I'm not sure, I'm not a child psychologist, but kids should not be presented ads for energy drinks/drink supplements (I wish I was kidding but I've specifically had to have a conversation with my daughter about why we're not buying the drink band owned by a certain YouTube celebrity who got himself banned from returning to Japan) nor for restaurants (especially not fast food!) nor for sketchy paid mod launchers for games (fuck you to the like only YouTuber who focuses entirely on Wobbly Life and is constantly advertising that!), nor most of the other things I've seen advertised to the kids recently
I mean it would be very space efficient to build such a space on some of where the parking lot is. A smallish parking space is 8'x16' so take 3 spaces, assuming each pod needs an exterior space of 4x8, stacked 2 high you can easily fit at least 32 pods in just 3 parking spaces with enough space leftover for hallway and a communal kitchen or something. They already have a public bathroom and shower facility so they'd only need the sleeping space and some communal recreation space that they can keep open 24/7 for their students staying in the pods
