My 14-year old daughter is planning a trip to London with friends on
Saturday. They need train plus tube tickets for one adult, one
16-year-old, who counts as an adult, and six children.

The simplest would be 'one's cheap Cambridge-London West Anglia only
offer, £18 for each adult plus £2 per child, total £48. If someone has a
suitable railcard it comes down to £12.50 plus £2 per child, total £37.

However, if they don't want a slow trip to London and prefer to use FCC
it all gets very messy. NRE only offers Day Travelcards, £22.50 for the
adults, £11.25 for the children, total £112.50. If they were doing that,
it would of course be better to buy a Network Card or two for £20 and
pay £17.60 per adult and £4.50 per child, total £82.20 or £102.20 if
they need two railcards.

However, there look to be unintegrated alternatives that are cheaper.
FCC offer Kids for £1 fares. NRE haven't heard of them but, from ringing
FCC Customer relations, they would appear to allow travel to King's
Cross for £1 each but no tune element. Then Child Travelcards could be
bought from LUL for £2 each.

I'm not sure what would be the best adult tickets with this option
because I don't seem to be able to bottom out the Kids for £1 fare
conditions. Either is would be 2 Day Travelcards at £22.50, making £63
in all, or 2 day returns to London terminals at £17.60 plus LUL
Travelcards at £6.30 (all zones - they might get away with less) in
which case the kids' cards would only be £1 each. So a total of £53.80.
All these are without railcards. If they have one it would upset the
calculations.

Any more?
