On a Tuesday afternoon in July, I intend to get the train from Watford Junction to London Euston, and then walk to St. Pancras.
I don't want to take the Overground, too slow.
I intend to take the LNWR trains, they take about 16-22 mins.
There will be two adults and two children, ages 9 and 12.
My query is about the fares, in particular the children's fares.
The TFL single fare finder says GBP 6.60 for adults, if paid by Oyster or contactless.

The two adults can use their debit cards, okay.
However, as the kids don't have Oyster cards or bank cards, it seems they must buy paper tickets?
I can't find these fares on TFL.
On the LNWR website, the fares seem much higher?
I welcome any advice, or comments.
