Greetings. My mother and I will be arriving into Heathrow at 9:30pm and want to take the Heathrow Express into London. We already know we want to buy the Two Together rail card (it will save on other tickets during the rest of our trip) and would like to use it to save on the fare on that train, but since we live in the US, we can't order it online. I understand that we can purchase it from any staffed counter, but I question if there will be a staffed ticket counter to purchase the Two Together card from by the time we clear customs?
If anyone can shed light on this, it would be much appreciated!
Thanks!
