An alternative, especially for children who love horses, is to head for Horse Guards Parade where the King's Life Guard change, at 11:00 Monday - Saturday and at 10:00 on a Sunday.
There you will find smaller crowds and no railings between visitors and the men and horses taking part in the ceremony.
Combine this with a visit to the Household Cavalry Museum where kids big and small can dress up in the uniform of a Life Guard or Blues and Royals trooper as well as see the horses being worked on in their stables, through a glass partition, and you might just have found someone's ideal day out.
