TOm, given the long list of your posts n this forum about past trips, I am surprised if you have not yet availed yourself of Rick Stteves Valuable and FREE dowoloadable Audio GUides. Just click on LH Column's List "Watch, read, Listen" and click GReece -- you will find a step-by-step Guide to ACropolis AND to the Ancient Agora, which you can download to your phones. Please note -- it's smart to give a listen before your trip, to understand it best. using these, you can go to Acropolis on YOUR schedule -- either early -early (8:15 in line; these days you need to register in advance), or late in day, 4 pm or so (just walk up to ticket office)... the crowds will be gone... you can also explore the Ancient Agora then... and an audio Guide will make sense of the ruins -- AND the stunning (reconstructed but authentic) SToa of Attalos, will impress even your museum-averse family.
As for the Acropolis Museum, you can go there (after the above in the Morning, or late afternooon) without subjecting your family to a "museum experience" and without entry fee (small tho it may be). That's because without entry fee you go up an escalator to its cafe.. Glassed-in terrace, lovely view of Parthenon, and a nice menu selection at decent prices; All Good.
IF then you should decide to "chance a Museum visit" and want an audio Guide, this website will give you admission tiicket PLUS a downloadable audio guide - https://www.getyourguide.com/acropolis-museum-l3766/audio-guides-tc144/ -- again, enabling you to fit it into your schedule. If not, I do at least recommend on the Museum top floor, a very amusing & informative 20-minute animated & live-action video constantly screening - that gives great history of the Parthenon and insights into its restoration. Interesting even for museum-haters.
