Your family might not need a Membership at all though - that's only if you need to download maps for offline use, or if you want to use different map sources... Gaia Topo and all the features besides mass-downloading are free.
Well yeah that's pretty critical (particularly as a differentiator vs Apple Maps). I'm in northern New England, huge portions of north NY and VT/NH/ME have no cell coverage at all. Let alone Canada. Online maps are nearly useless not just for hiking and general backcountry work but even regular driving to job sites. My own town has no cell at all downtown, not just "no LTE", no cell coverage period. If you've ever looked at coverage maps the phone companies put out showing huge areas all nicely lit, know that they are flagrant lies that are finally even getting government attention. If you're interested, first search result article that came up is one from last year on VT going ahead and actually spending 6 weeks driving around the whole state testing themselves:

A touch different then what the cell companies claimed :).
Thank you very much for the reply though! It's good to know that, with the caveat of no individual profiles, an account could be shared around a bit without getting auto banned; I know some services do track that. FWIW, might be worth considering as a some-day feature to have a cut-down version of your Teams offering or a bundle as an official Family Plan, for a bit more money than standard with "up to 6" (or 5 or whatever) profiles. At any rate though, good to have more options to consider in mapping.
