Where did Prince Philip and Queen Elizabeth first meet?

According to a web site.... "Philip was born Philippos Prince of Greece and Denmark on the Greek Island of Corfu in 1921. His father was Prince Andrew, younger brother of King Constantine of Greece, and his mother Princess Alice of Battenberg. He is a great-great-grandchild of Queen Victoria though his mother's family. The monarchy of Greece was overthrown in 1922, and George V sent a Royal Navy ship HMS Calypso to rescue them. The one-year old Philip was carried to safety in an orange box. The family lived in Paris but his parents' marriage broke up and Philip went to school in England, Germany and then Gordonstoun in Scotland where he was head of the school cricket and hockey teams and became head boy. Princess Elizabeth and Philip first met when they attended the wedding of Philip's cousin, Princess Marina of Greece to The Duke of Kent, who was an uncle of Princess Elizabeth, in 1934."
