A friend and I are going to spend a week in London in March. Both being first-timers, we will be seeing all the primary palaces, museums, etc. It looks like the way to go is a 7-day Travelcard purchased at a railway station is the way to go to get the 2 for 1 discount for several of the places we intend to visit.
We will fly in to Heathrow. Is there a place at the airport to get a railway station Travelcard? If not, what is the closest one we could go to?
Thanks in advance.
