Extra dates for its popular two-day coach tours to Warner Bros’ London studios are available from July through to end end of the year, with prices from £159pp (based on two sharing).

Prices include return coach travel, one night’s B&B accommodation, studio admission and a London excursion. National is offering pick-up points across the north west, north east, Yorkshire and the Midlands.

Guests can visit Diagon Alley, learn the secrets behind the special effects in the Harry Potter films, and get up close with some of the iconic props from the wizarding world.

Winter departures, meanwhile, give fans a chance of experiencing Hogwarts in the snow too, and sit down to a Christmas feast in Hogwarts’ great hall.

Claire Dutton, trade sales manager at National parent JG Travel Group, said: "These breaks provide agents with a really great hook to drive sales.

"Tickets are always in high demand for this attraction so using windows to promote a coach break with ticket, accommodation and coach travel for one great price can be a real draw – it’s all organised and quick to book."

Dutton added sales resources and social media assets were available from National’s agent Facebook page.
