I seem to have been going around in circles but what I THINK is the simplest and cheapest way to travel will just be PAYG just on our debit cards for both of us because of the price cap.
We wont be using peak time tubes.
We don't live in London, dont go very often, and don't have Oystercards.
Will only be travelling in zones 1 and 2
Will be there two days.
I have looked at the prices for day travelcards, but for me it is more expensive to buy one at £15.90 because its zones 1-4 The price cap for zones 1-2 is £8.50.
For DS who is 14, it looks like if I get him a travelcard, its slightly cheaper than the price cap as the child travelcard is £7.90, but difference of 60p so not sure its worth bothering.
Does this sound right? I think it does - I just needed to write it down!
