He could marry Ginny. They already have a strong connection in the original series. In a Vegas - themed story, they might decide to run off to Vegas for a fun and exciting wedding. It would be a way to break free from the traditional wizarding wedding norms.
Hermione could be another option. Their relationship in the books was always complex and full of mutual respect. In a Vegas fanfiction, perhaps they realize their feelings for each other in a different light during a trip to Vegas and decide to get married on a whim. It would be a very different take on their relationship compared to the original story.
He could marry a Muggle he meets by chance in Vegas. Maybe a singer or a waitress who has a big heart and an open mind towards the strange things Harry might do or say because of his wizarding background.
It could be a powerful dark wizard who has escaped from Azkaban and has made Vegas his new lair. He's using the chaos and glamour of Vegas to hide his dark magic activities, like creating dark spells and recruiting followers. Harry would have to face this wizard to protect both the wizarding and Muggle worlds.
Well, Harry could marry one of the veelas. Given their beauty and allure, it would add an interesting dynamic to the story. Their relationship could involve Harry having to deal with the jealousy of other wizards and also the cultural differences of the veelas. Or he could marry a descendant of one of the founders of Hogwarts. This would tie in a lot of Hogwarts history into their relationship, and their wedding could be a grand event that unites different factions within the wizarding community who have ties to the founders.
Obviously, Harry Potter himself would be a main character. He'd be the one leading the way through the Vegas challenges, using his Gryffindor courage and his skills as a wizard.
Obviously, Harry Potter himself would be the central character. Hermione could be part of the harem, as she has always been close to Harry. Luna Lovegood might also be there, with her unique and dreamy personality. Additionally, some new original characters could be introduced, like a powerful witch from a Vegas - based wizarding family.
Umbridge could also be a likely candidate. Given her power - hungry and controlling nature in the original series, she might arrange a forced marriage for Harry to gain more power and influence within the wizarding community. She would probably do it under the guise of some 'for the greater good' excuse.
Harry Potter himself could be the main character. He might be looking for a break from his usual heroic duties and end up in Vegas, where he meets someone unexpected and gets involved in a wedding challenge. It could be a new character or even an old acquaintance from Hogwarts, like Cho Chang, and they decide to go through with the challenge together.

Well, perhaps Harry and his friends could visit the famous Vegas shows. They might be amazed by the magic tricks there, thinking they're similar to the spells they know. And they could explore the glittering casinos, but of course, not for gambling in a proper 'Harry Potter' way. Maybe Hermione would be interested in the libraries in Vegas, if there are any special ones.
Well, in a 'Harry Potter Marries in Vegas' fanfiction, it could start with Harry being frustrated with the wizarding world's formalities regarding relationships. He goes to Vegas for a break and gets drunk. There, he meets a girl who seems to understand his struggles. They have a wild night and end up at a wedding chapel. After the marriage, he has to figure out how to incorporate her into his life in Hogwarts or wherever he is living at that time. Maybe she has some magical abilities he doesn't know about at first.
