The thread title says it all really...
We'll be in London for a day between Christmas and new year. We'll be coming in on the train from Hertfordshire. First stop, which will be non negotiable for both boys and Dad, is the arsenal stadium. We'll also probably head to Buckingham palace for the changing of the guard at 11.30. We're quite happy to spend all day and head back late but want to make the best use of our time without rushing too much.
Any suggestions? Both boys are mad on star wars, football and Lego if that helps!
