Thanks, I reviewed the threads of thursdaysd and a lot of questions were answered.

then when you get to Kings Cross you can but your daily PAPER travel cards.>

From Kings X to where? You have to buy a ticket to somewhere - like Kings Cross to Faringdon (national rail station the next station south of Kings Cross I think) - just buy the cheapest ticket to a station in London -just a techincality does not matter where. Ask at ticket window.

Buy a return ticket with the dates you will be using 1/2 Fare thing?

Not sure asking questions - it can be a very complex thing to explain.

>>From Kings X to where? You have to buy a ticket to somewhere - <<

No you don't. One-day paper travelcards can be used for daily transport and don't have a 'destination'.

From Kings X to where?

Faringdon for example -if such a thing is possible - a return ticket valid for say the week you'll be in London and using 2 for 1?

Just like return ticket from Gatwick covers you the whole time in London.

Not sure a Travelcard is worth it with going to five 2-4-1 attractions.>

on different days -my point- folks here before who were locals said you could buy a paper train ticket to and from London (even stations within London) and use that for 2/1 discounts the whole validity period, negating having to buy paper travel cards.

Maybe someone will know the definitive answer to this?

This kind of exlains it:

Did you read the link?

"If you don't have a train ticket, then the Travelcard London public transport pass is the way to qualify for the promotion. Nearly every visitor to London will have to buy a Travelcard or Oyster public transport pass to get around. The question of which, Travelcard or Oyster is very complex - but the savings you can make using a Travelcard with 2 for 1 admissions will far outweigh any savings of Oyster over Travelcards just for the transport."

I understand that but TCs can get expensive if folks don't use TfL much - like Gatwick -buy a return train ticket on paper from there to London and back gives you right for 2 for 1 your whole time there. No need to hassle with getting paper travel cards (having to go to a proper train station to do so so you get that national rail logo on the ticket that is needed to qualify for 2-4-1)

Rather I pop into any London train station and buy a ticket from some nearby suburban station to London for a certain date and one for back out for a different date -using it the whole time for 2 for 1- that's the question?

I believe this was what London experts said could be done -anyone know. My brother and wife are going to London soon and I'd like to know for them.

I guess I'll start a separate post rather than bog this down anymore.
