The experience will begin with themed welcome drinks and canapés, followed by a three-course meal in the Great Hall, where tables will be decorated with flowers and candles.
Following dinner, attendees will be granted after-hours access to the studio tour, with sights such as the Gryffindor common room, Dumbledore's office and the Malfoy Manor dining table all available for viewing.
Ticketholders will then be treated to a drink at platform 9 3/4, at which point they will make their way along Diagon Alley to the Hogwarts castle model, where tea, coffee and chocolates will be served.
The evening will come to an end when guests are ushered back to the tour's lobby area, where they will be able to pick up their 'chosen wand', before hopping back on the shuttle to Watford.
Tickets to the experience, which lasts approximately six hours, go on sale tomorrow (13 January) and they are priced at £247.50 each or £495 per couple.
Warner Bros also opened up its Harry Potter studio tour over the festive season, where it hosted a one-off shared Christmas party.
