I am 13 and I want to go to London but I don't know how to come up with the money any advice?
You can't travel on your own at your age, you will need a guide/relative to be with you, so I suggest that you save up your money and then spend them on the trip when you are older.
You can't go by yourself at 13. So, tell your parents that's where you want to go for a vacation one year. Save up money to help them.
wait till your around the age of 16 and keep on saving money so then you can go or you can go with me I used to live over there.
