It is, I walked past it yesterday.

Somebody told me that travelcards are better if you're using the 2:1 for the attractions. So I'm thinking of getting it. What do you think?

If you're using travel cards for the 2-1 attractions you MUST buy them at a train station.
That's a mainline train station, not the London underground!
But please, don't take what 'someone said' as your guide - read up about it and fully acquaint yourself first. Otherwise you're just throwing money away.
I sometimes used to buy just a single ticket from a previous station to take advantage of this, but now I get free transport and 'senior's reductions everywhere so am not up to date with how this may currently work.

If you really need a paper train ticket to take advantage of some of the 2 for 1 ticket offers, it is not exactly hard to find many discarded train tickets lying on the ground. My experience when using the 2 for 1 ticket offers is that most of the time you just present the coupon and they never even ask to see the ticket.
