Need some advice about travelling around London please!
I'm taking my 2 DS to Lodnon for the day next week. We will get the train to King's Cross then plan to go to the natural history museum, then down to Tower Bridge, Buckingham Palace area for some sight seeing then back home.
I assume best way to get round will be the tube, I'm a bit nervous about this with how busy they are and I will be on my own with 2 children, but also what is the best way to pay for the tube, I don't want to be faffing around on the day.
Any advice on the best way to get around with young children and how to pay?
