The official page for Universal Orlando Resort's Wizarding World of Harry Potter - Diagon Alley's main attraction, Harry Potter and the Escape from Gringotts, notes that Harry, Ron and Hermione will be seen on the ride. Not much has been revealed about the Gringotts adventure, though theories have come across that it will be similar to the cart ride from
Harry Potter and the Deathly Hallows: Part 2, as shown below. Though please note that it is unconfirmed how Harry, Ron and Hermione will be featured (as video, audio, or old footage), as neither Daniel Radcliffe, Rupert Grint or Emma Watson (or even Helena Bonham Carter) have confirmed being back for the attraction.
