I spent 5 nights on Cunard's luxury Queen Elizabeth cruise ship. Here are all the hidden references to royalty I discovered on board.

The British cruise line returned to sailing with a Western Europe voyage in October, its first voyage to leave the UK since the pandemic.

As a journalist who covers the British royals, I was intrigued that the ship is named after Queen Elizabeth.

The Queen Elizabeth, launched in 2010, is the third Cunard ship to take the name, according to its website. The original RMS Queen Elizabeth was in service from 1939 until 1968, and the Queen Elizabeth 2 was launched in 1969 and retired in 2008.

Queen Elizabeth II was at all three naming ceremonies, the website states.

The cruise line has been linked to royalty since 1934 when it named a ship after Queen Mary, according to its website.

The Queen Mother, Queen Elizabeth II, and Princess Diana all visited Cunard ships over the years. Elizabeth II made history by traveling on the Queen Elizabeth 2 in 1990, marking the first time a reigning monarch had sailed on a passenger ship operating a commercial voyage, according to Cunard.

My room had a king-sized bed, a TV, a tea and coffee station, a mini-fridge, a desk, and two sets of drawers. It also had several hidden references to royalty, including in the Cunard logo.

The lion rampant was chosen "because of its association with the Royal Standards of English and Scottish Monarchs," Cunard historian and the cruise line's former PR manager, Michael Gallagher, previously told Insider.

The Royal Standard is a traditional banner with the royal coat of arms, usually flown in the presence of royalty, according to the royal family website.

Gallagher said the lion rampant was also considered to be the king of beasts, "which fitted with Cunard's Atlantic supremacy."

After seeing the logo on the pillows, I couldn't help but notice it everywhere I turned.

It was on a pair of complimentary slippers and bathrobe left for me in my stateroom, and also featured on menus, deck chairs, and the ship's stationery.

Quercus manufacturer Penhaligon's has a Royal Warrant, something which is provided to companies that provide goods or services to the Queen, the late Duke of Edinburgh, or Prince Charles, according to the official Royal Warrant website.

Hildon water was also served in the ship's restaurant and bar areas.

Godiva chocolate has a special connection to the Belgian royals. In 1968, it was given a Royal Warrant, making it the official chocolatier to the Royal Court of Belgium, according to its website.

The Lido buffet restaurant offered afternoon tea every day between 3 p.m. and 4:30 p.m. during my voyage.

Afternoon tea was introduced to the UK in the 1840s as a private social event for ladies before dinner, according to Afternoontea.co.uk.

It was popularized by Queen Victoria, who was a "PR machine for it," Prince Charles' former butler Grant Harrold once told me.

"And as we know, when a royal starts something, it becomes the fashion," Harrold said.

Due to Cunard's COVID restrictions, guests were served by a staff member rather than serving themselves at the buffet.

Croquet is a sport that involves hitting wooden or plastic balls with a mallet through hoops.

Photos of the Queen and the late Prince Philip playing croquet together when they first met in 1939 were released by the Ministry of Defence earlier this year, The Mirror reports.

The then-Princess Elizabeth would have been 13 years old at the time, while Philip would have been 18.

The Queens Room is the largest ballroom at sea and "the social hub of the ship," according to Cunard's website.

When I was on the ship, the room was used to host social activities during the day, such as dance classes, and in the evening, guests were treated to live music and ballroom dancing.

There were other royal paintings scattered across the ship, including one of Balmoral Castle (the Queen's residence in Scotland), and one of Queen Elizabeth and Prince Philip.

The cabinet displayed black and white photos and newspaper clippings from royal visits to Cunard.

It also displayed Queen Elizabeth II's coronation book and King George VI's coronation medals.

The photo was dated December 28, 1949.

The caption read: "The Duke and Duchess of Windsor arriving yesterday aboard the liner Queen Elizabeth. They will stay in New York for a month and then go on to the Duke's ranch in Alberta, Canada."
