Personally if with kids I wouldn't bother as the saving isn't that huge compared to 4 tickets at £40, a night in a hotel (so you don't miss your connecting flight) and more flying. The £90 will go up to £120 in November, but suspect that will be after you fly.
£90*4 is usually considered to add up to £360 rather than £280 (
). I agree that saving is probably not worth it if it adds to routing, but this is likely to be so only if the OP has a direct flight ex-UK. If award availability is on a US-bound flight from DUB or FRA anyway, it does not add anything to routing to start the redemption from there and get a cheap ticket to there, with the caveat that it would probably require an overnight to avoid any risk of misconnect as it would then be on separate tickets, and therefore not protected in case of delay/cancellation of first flight.
