Definitely the Weasley family. Molly and Arthur Weasley would be very much involved. Molly would be all excited about the wedding preparations, fussing over Ginny's dress and the food for the reception. Arthur would be there to offer his support and probably share some interesting wizarding stories. Ron and Hermione would also be there. Ron as Harry's best friend would be part of the pre - wedding jitters and celebrations. Hermione would be helping Ginny with all the details, like choosing the right flowers and making sure the wedding venue is decorated perfectly.
Well, Harry and Ginny are at the center of it all. But don't forget Hagrid. He could be the one to bring in some really special and huge wedding gift, like a magical creature for the couple's new home.

And then there are Ginny's brothers, each with their own personalities, who would contribute to the chaos and fun of the wedding preparations.
In some harry and ginny wedding fanfic, there could be a plot where an unexpected guest arrives. Maybe it's a former Hogwarts classmate who has been away for a long time.

These little details can make the story really engaging.
One interesting plot could be the inclusion of magical elements in the wedding decor. For example, floating candles that change colors according to the mood of the couple. Another plot might be the presence of unexpected guests, like a long - lost wizard relative of Ginny's who brings a special family heirloom as a wedding gift. Also, a plot could revolve around Harry and Ginny's nervousness before the ceremony and how they overcome it with the support of their friends.

And Hagrid, who has been like a father figure to Harry in a way, would also be there to celebrate this happy occasion.
