We will be spending a week in London this fall - two adults, and two kids between 11 and 15. Other than the travel to/from Heathrow, we plan to use public transit. This forum was helpful in steering me to the choice of the adults using our credit cards, while getting Visitor Oyster cards with the children's discount for the kids. I'm a little confused as to where the latter are available.
The TFL site is explicit in saying "You can't buy a Visitor Oyster card in London" and we need to order these before we leave. The online site shows +10 GBP for two cards and the cheapest delivery method to the US adds another 9 GBP to the actual amount loaded on the cards.
To further confuse the matter, I understand the Visitor Centers are where we can have the discount added to the cards, and the one in Heathrow is closed on Sunday when we arrive, while the one at Kings Cross (where we are staying) is closed on both Sunday and Monday. That is 2 of the 6 days we are there. Is the additional 19 GBP worth it for 4 days? Or am I getting something wrong?
Thanks in advance.
