Massachusetts blogger and lifelong royals fan Sarah Binns traveled to London for the royal wedding. Read her story below and learn more about her journey tonight on a special two-hour "20/20" at 9 p.m. ET.

The royal wedding morning dawned as chilly and overcast as the night before, but not even the typical English weather could weaken the fire in the hearts of the crowds gathered along the Mall.

Early on Thursday afternoon, I introduced myself to a group of students studying at a university in Wales -- they came to the wedding at the end of their Easter break. My new friends kindly allowed me to place my sleeping bag next to their tent (as well as their collection of miniature royal family dolls), giving me a front-row view of the Mall and the royal wedding procession today. For the few of us who managed to grab an hour or two of sleep amid last night's near-constant cheering, singing and sometimes drunken-revelry, we woke at 5 a.m. to find a tent city had grown up around us -- people had begun piling onto the Mall, as many as 12 deep. Considering that many of them had to use stepladders to see any of the action, I was very lucky with my barricade-bordering spot.

Chills of anticipation shuddered through me many times during the day, and the enormity of the event left me speechless as I watched thousands of people wave their flags in unison to the sound of the British national anthem, "God Save the Queen." The organ music piped loudly through the Mall, making all of us feel that we, too, were inside Westminster Abbey. William and Catherine's vows, though taken from a standard prayer book and recited before a worldwide audience, sounded so genuine and happy that I was moved to tears; I was not alone in crying. By the end of the ceremony, the crowd was visibly moved and eagerly awaited the return of the newly married couple.

My mission is accomplished, and I have now seen William, Catherine and the queen in person. They, along with the other members of the royal family, glowed as they passed us, waving as they have waved to millions of others -- but I felt as if I could have been the only one on the Mall when the Duchess of Cornwall looked right at me with a dazzling smile.

My fears of pickpockets and of running into anti-royalist protesters were unfounded. The crowd was euphoric, international and surprisingly friendly, given the lack of sleep for most. We, the hundreds of thousands watching as they proceeded, fell head-over-heels in love with the newly minted Duke and Duchess of Cambridge. They begin their fairytale as mine comes to a close, but I don't think anyone who watched the pageantry can deny that this time it's true: William and Catherine will live happily ever after.
