Planned to go away as a family and booked train tickets using a railway family card (dc2 is less than 16yo).
Unfortunately , dc2 can’t come anymore so there is only the three of us, all over 16yo.
Seeing that we’ve paid for all the tickets anyway, would it be ok to still use those tickets to travel? Not fancying paying another couple of hundred pounds to buy what we already had iyswim
