Nothing says royal wedding quite like a horse-drawn carriage, and Meghan Markle will surely be atop one after she weds Prince Harry on May 19.

Carriages And Convoy Routes

The only question is which carriage? The much-awaited procession post-wedding is a significant affair as it's the first glimpse well-wishers will get of the newlyweds as they line the streets surrounding Windsor Castle. And apparently, the royal family has an entire fleet of carriages to choose from.

According to a report from People, Queen Elizabeth will be choosing for the couple. After all, the carriages are all parked in what's dubbed the Royal Mews in the Buckingham Palace.

When Prince William and the Duchess of Cambridge Kate Middleton got married in 2011, the couple used the century-old Imperial State Landau in London. This particular carriage is often in the capital city.

Majesty magazine managing editor Joe Little speculates the younger prince and her bride will likely opt for a more understated ride.

"My guess is that it will be an Ascot Landau," Little says. "It's not as regal or grand as the Imperial State Landau, but it is perfect for the streets of Windsor."

Another Ascot Landau may also follow with the best man (also known as the "supporter") and a handful of junior attendants. For Prince Harry's wedding, this will likely be his brother Prince William along with the latter's children Prince George and Princess Charlotte.

The royal convoy will go from St. George's Chapel, then take Castle Hill out of Windsor. The carriage ride will then pass through Windsor Town through High Street, Sheet Street, King's Road, and Albert Road. The procession will go back to Windsor Castle via the Long Walk.

"They hope this short journey will provide an opportunity for more people to come together around Windsor and to enjoy the atmosphere of this special day," an official statement from Kensington Palace says.

Royal And Ultra-Exclusive Guest List

While the upcoming nuptial is undoubtedly the biggest wedding of the year, the affair is a closely guarded one. Very little has been revealed, including the much coveted guest list.

The St. George's Chapel has an 800-guest capacity, which is quite modest for royal standards.

Relatives of the royal family alone already count for more than 50 people. Britain's highest political figures will likely secure an invite, while a number of foreign officials may also be present.

With Prince Harry's history as an Apache helicopter co-pilot, there's also a big chance that British military members will be well-represented at the royal wedding.

And of course, close celebrity friends will be among the attendees. Potential wedding performers include Elton John, Ed Sheeran, Coldplay, Adele, and Joss Stone.
