The spot, which broke during GMTV this morning and will run for two weeks, features Alton Towers customers providing details of the promotion while riding one of the park's rollercoasters.
The riders struggle to say their lines due to the high velocity experience of the rider, so their words are accompanied by subtitles at the bottom of the screen.
The Sun is also running the Alton Towers promotion for the next 11 days in the newspaper, offering a potential £76 saving if readers collect seven differently numbered coupons.
The promotional push comes ahead of the launch of the park's new rollercoaster Th13teen, which promises to plunge riders into "the gruelling Dark Forest".
Tickets will be allocated on a first come first served basis. Readers will be able to use them at any time until the park closes for the season in November.
WCRS has created a number of TV campaigns for The Sun since picking up the business from Euro RSCG in November 2008.
In September last year it rolled out an ad starring its football columnists Ian Wright, Terry Venables and Harry Redknapp to promote the newspaper's sport section.
