Albert Edward and Alexandra undertook a six-month tour taking in Austria, Egypt and Greece over 1868-9, which included visits to her brother, George I of Greece and, for her only, to the harem of the Khedive Ismail. In Turkey she became the first woman to sit down to dinner with the Sultan Abdul-Aziz, and later the royal party visited the Crimean battlefields. Albert Edward and Alexandra made Sandringham House their preferred residence, and their marriage was in many ways a happy one. However, Albert Edward did not give his wife or children as much attention as she would have liked, and they gradually became estranged, until his serious illness in the early 1870s brought about a reconciliation. Their relationship had its ups and downs over the years. Albert Edward, even after winning back his wife's affections, continued to keep mistresses, among them the actress Lillie Langtry; Daisy Greville, Countess of Warwick; humanitarian Agnes Keyser, and society matron Alice Keppel (the present Duchess of Cornwall's grandmother). Most of these were with the full knowledge of Alexandra. It is commonly stated that the Queen allowed Alice Keppel to sit by the King's bedside as he lay dying. However, Alexandra was wholeheartedly against it; Keppel forced herself on Sandringham House, and when asked by the Queen to leave the bedchamber, she created an embarrassing scene and had to be escorted out. She merely tolerated Keppel, but never accepted her. Alexandra did not like the fact that Keppel appeared everywhere that she and Albert Edward went. Alexandra herself remained faithful throughout her marriage. Edward is also reputed to have kept company with Sarah Bernhardt and La Belle Otero.
