Given that (I think) a 3-day Travelcard was just priced at three times
a One Day Travelcard, and you can still buy the latter on paper, you
could just buy three of those each.

Another argument against buying 3-day Travelcards is that they no
longer exist - they were withdrawn at the beginning of the year.

Failing that, cash the Oyster cards in at the end and get a refund of
the deposit and balance.

The TfL website confirms that this is possible:
You can take your Oyster card to a Tube station ticket office for a refund of your unused ticket or travel
value and the £3 deposit.

Using Oyster PAYG might well work out a little cheaper for the OP, if
it turns out that he doesn't need zones 1-6 on all three days; or if
he doesn't need to travel during the morning peak. It certainly won't
cost any more than buying paper tickets - the only downsides are
having to visit a tube ticket office at your last station (though I'd
imagine the major rail termini and Heathrow are used to this kind of
transaction), and possibly being left over with some of our funny
English money.
