EARLY risers are making their way to Windsor to bag a prime spot for the Royal wedding.

Prince Harry will marry Meghan Markle in a spectacular ceremony later on Saturday.

Passengers on the first train out of London Waterloo included four women who work as cabin crew for a Canadian airline.

They joked they had won the "golden ticket" by being in London on layover on Harry and Meghan's big day.

"It's a once in a lifetime opportunity. We are sending our love from Canada," Cara Bonhage said.

"It's going to be really exciting."

Her and friends, Deb Penman, Marlene Diggens and Nancy Botelho said they plan to stand at the end of the parade route to catch a glimpse of the couple as they pass in their open-topped carriage.

"We want to be part of history," Ms Botelho added.

Irene Bowdry, a lawyer from California, was on the 5.50am train from Waterloo to Windsor with four friends from the US.

She said: "My mum actually lives around the corner from Meghan's mum in View Park in Los Angeles.

"We booked as soon as it was announced. An American in the royal family, isn't that so exciting?"

Also on board was German surgeon Ralph Dubitscher, who said he came because "it's the last chance to get a royal wedding for, what, 30 years?".

Visitors are pouring into the town of Windsor, where excitement is building ahead of the royal wedding.

Some superfans have been camped out for days to secure their spots to see Harry and Meghan's carriage pass.

John Loughrey, 63, from Streatham in London, has been in position for four days at what he's dubbed "crazy corner" - the junction of High Street and Castle Hill.

"This is a very special day today for Prince Harry and Meghan, going into St George's Chapel and Prince Charles will walk Meghan down the aisle," he said.

"We want the carriage to slow down when it comes around this bend to see the wedding dress and wedding ring and Prince Harry and Meghan smiling at the world.

"We are going to have one big party in Windsor and around the world."

Seasoned royal-watcher Terry Hutt, 83, spoke of the romance of the occasion.

"What makes this a special wedding is that they have gone out and met each other and fallen in love, and that's quite natural," he said.

"They broke all the rules and they are actually bringing the royal family forward.

"I think we're all going to be happy with the result. If his mother was alive, she would be too.

"She left something of herself behind and it was the two lads."

Slough station has made spectators feel welcome with a sign celebrating the nuptials.

The dot matrix board said: "All aboard the royal wedding special to Harry & Meghan Central."

At 6:30am, a golf buggy carrying TV host Phillip Schofield made its way down the Long Walk, to cheering from the crowd.

The ITV anchor for the royal wedding coverage gave them a wave and said: "Nice to see you."

Jo Pratt and Laura Hamlin travelled from Horsham, Sussex, arriving at the Long Walk at 4am.

"It was freezing cold but we are very excited. We are hoping that they'll become the Duke and Duchess of Sussex. That would be fantastic," said Ms Pratt.

Christine Clancy from Virginia in the US was on one of the first trains into Windsor and was sporting thumbnails and shoes decorated with the Union flag.

Ms Clancy said: "I've always been a royal fan - not an extreme one - I just love British history and love the royals. I just wanted to be part of a part of the wedding celebration.

"It would have been nice if Meghan's dad was walking her down the aisle, everyone was expecting her mum to do it, but Charles - he'll be able to do it with his eyes closed."

Sheila Tinning and her husband Paul are celebrating their 45th wedding anniversary today.

Last night, the Cumbrian couple had the fortune of meeting Prince Harry and the Duke of Cambridge on the pre-wedding walkabout.

"I shook William and Harry's hand last night. It was fantastic," said Mrs Tinning.

"There were two cameras behind me and lots of police and we realised something was happening. We couldn't believe it. I wished them a lovely day today and they said thank you very much.

"There was a little boy in front and Harry was brilliant with him. He asked where he was from and how long he had been waiting.

"I never expected that," she added.

Meghan's Suits co-star Patrick J. Adams tweeted: "70 years ago my grandparents, Patricia and Cedric Marsh were married in a small service in Windsor, England. Just found that out. Already getting misty... #royalwedding"

Cornish trio Annabelle Bennetts, Sarah Hawkins and Samantha Burdon arrived at 4am to get a good spot.

Sporting home-made red, white and blue hats, they wanted to wish Harry and Meghan "the very best of luck" in their marriage.

Leila Souza, 67, and Adela Welch, 63, travelled from Tampa, Florida to watch the wedding.

The pair have booked a "VIP spot" in a cafe along the procession route to ensure a good view of proceedings.

They have made a sign featuring a picture of Princess Diana on her wedding day, with the words "here in spirit".

Ms Souza said: "When she died Prince Harry was just a little child. We all grieved.

"His mother will be very, very happy today, so she's here in spirit."

Arlene Prinsloo has travelled all the way from South Africa for the royal wedding.

"I'm here for six days," she said.

"After the weekend in Windsor I'm planning on seeing the Diana exhibition at Kensington Palace. I love the royal family. It started when I saw a movie about Mary, Queen of Scots.

Sat in front of the ITV studio, she said she was excited to meet weatherman Alex Beresford, but had to ask who he was as she was taking a selfie.

Her friend, Adele von Zeuner, a South African living in London, said: "The only day I skipped school was for the wedding of Charles and Diana. I was 17 years old and my parents never knew."

Tennis player Serena Williams appeared to confirm her attendance in Windsor as she tweeted that she was "getting ready for my friends wedding", and told people to keep an eye on her Instagram story for updates.

Local trio Farkahanda Ahmed, 35, her mother Shakeela Ahmed, 52, and Farah Muktar, 39, arrived at 4am to make sure they got a good view of Harry and Megan's big day.

The group, from nearby Slough, donned matching Union flag hijabs and made their way to the parade route just after breaking their Ramadan fast.

Farkahanda, who works for her local council, said: "It's a proud moment for us - times are changing. Who would have thought a Hollywood actress would become a British princess?

"We are proud to be British and we wanted to come here and show our support.

"We've met so many people - people from America, Scotland and all over the place and it's just so nice for the community to get together."

She added: "We are Muslims and we're proud to be British and we wanted to come here and show the support from our community. We are British Asian - born and raised here and we're all here to celebrate."

The Archbishop of Canterbury, who will be officiating the ceremony in Windsor, tweeted: "Praying for Prince Harry and Ms Meghan Markle today. May it be a day of joy and celebration as they commit their lives to each other before God - and may we all share in that joy with them."

Buckingham Palace said: "The Queen has today been pleased to confer a Dukedom on Prince Henry of Wales.

"His titles will be Duke of Sussex, Earl of Dumbarton and Baron Kilkeel. Prince Harry thus becomes His Royal Highness The Duke of Sussex, and Ms Meghan Markle on marriage will become Her Royal Highness The Duchess of Sussex."

The party's started early for some in Windsor.

Mother-of-four Rachael Carter-Eagleton popped open the prosecco just after 8am.

"I'm just so happy for Harry," said the Londoner, a regular at royal events.

"I can't wait to see what Meghan's wearing."

Caroline Wagstaff slept on the grass along the Long Walk last night, but was quick to open a bottle of English champagne this morning.

Draped in British flags and wearing crowns, her and her friend Rebecca Hilliard said they were enjoying the atmosphere.

"We woke up around 4am when the crowds started arriving," said Ms Wagstaff, who lives in Windsor.

"It was a bit chilly overnight but we've been up for so long now it feels right to open the English champagne.

"I made the crown a few years ago and everyone loves it. It's a great atmosphere," she added.

Windsor locals Elizabeth Hughes, 19, Brooke Beldom, 13, and mum Laura, 40, along with Claudia Smith, 21, and mum Leigh, 48, were head-to-toe in red, white and blue for the royal wedding.

Laura said: "We wouldn't have missed it for the world - we're here for the atmosphere."

The group joked they were "more Harry fans than Meghan fans".

"We've got three lovely girls here and they've missed out!" Laura said.

She added: "But still, Meghan's a lovely girl."

Their message for Harry and Meghan was: "Congratulations, good luck, all the best."
