I will be leaving soon for a trip to London with my two teenage children (18 &15). We will only have 4 days to see the sights, so we will try and focus on seeing as much as we can in that short time. I was thinking about buying single fare tickets when we land in Heathrow on the underground to take us to our hotel near Bank & Monument stations. I would like to take advantage of the NR Travel Card 2 4 1 deals for the Tower of London and possibly the City Cruise. We will be leaving London on day 5 from Bank Street DLR to London City Airport. Other than London City Airport, I don't expect we will be travelling out of zones 1-2.
Cost wise, Is the NR travel card the way to go or would we be better off buying the Oyster Visitor Card? I am also under the impression that if I buy the NR 7 Day Travel Card, we will need to bring passport size photos with us for the card?
Appreciate any advice as I am still not sure what our best options are.
