At Caesars Palace in Las Vegas, Megan and her newly 21-year-old sister, Caitlin, were lazing by the pool when a gaggle of guys strolled by their lounge chairs. One voice stood out to Megan. Mark's accent was British and dreamy.
She went for it: "Hey, how it's going? Come over here!"
Sharing a few rounds of drinks, she learned that Mark was visiting Vegas from Hull (a four-hour drive from London) for a five-night vacation. At first, she didn't believe him, so she asked for ID. Mark was leaving the next morning to head back to the United Kingdom. Megan scored a poolside kiss, and Mark asked to see her that night.
Later, they escaped to Caesars' swank Chateau Lounge for a few more toasts before meeting up with Mark's friends in their sprawling Hangover-style suite.
The next day, Megan and her sister crawled out of bed to visit the site of the reality TV show Pawn Stars. She got a phone call from Mark. He wanted to see her before he left.
"I'm glad I saw her," Mark recalls. "I was thinking about her all the way home."
Just a week after returning to England, in May 2010, Mark booked a flight to see Megan in Buffalo, N.Y., where she was living. In October, Megan traveled to England. Between trips, they used BlackBerry Messenger, and they spoke on the phone on the weekends. They emailed, they wrote letters. Anything to stay close.
"It's so important to disclose the tiniest details of your day," Megan says of long-distance relationships. "Those details make your significant other feel like they're part of your day, too."
The couple saw each other four times before they got engaged. When Mark came to Buffalo again, nearly a year after they first met, they roamed up to Toronto for the weekend. In their hotel room, right before they left for dinner, Mark proposed.
The couple married in Buffalo on Queen Elizabeth's birthday, two weeks after Mark moved to the United States, then they moved to Largo. During their Catholic ceremony, the priest said: "I guess what happens in Vegas doesn't stay in Vegas.
