As lots of you know, I will have my 15 yr old grandson and my 11 year old granddaughter with me in London this coming spring for 10 nights. I already have a regular Oyster card (not visitor) with a Railcard discount attached to it, but I'm trying to figure out what I would get for them.
It looks like my best option is to buy them each an Oyster card and then get the Young Visitor discount attached to it. Does that sound right? The last time I was there, I was able to get my discount attached to the Oyster card while I was at Heathrow, so I'm assuming I can do it there, too.
