The film is available on DVD & blu-ray, & I assume streaming somewhere. Not only is watching that cheaper than seeing it on Broadway 6 times, she might learn a thing or two more by watching it.
Regarding the show closing, Broadway is cyclical and sooner or later something else will take its place. In a couple months a bunch of new shows open. Let's hope something there will be OK.
If they can actually fix the book of Camelot so it doesn't drag, that could be excellent as it has some very nice songs.
