I'd like to take my two nieces out for their birthdays. I also have two girls of my own. The four girls are aged 4, 7, 11 and 14. Does anyone have any ideas on what all the girls plus two adults can do around London that won't cost a fortune? I looked at getting tickets for The Lion King and we're looking at hundreds of pounds for 6 seats.
Last year we took them to the Science Museum which was a hit!
