"Shrek The Musical" sets up swamp in San Francisco's historic Orpheum Theatre, and tickets to all evening performances through Jan.1 have been reduced by as much as 50%.

Orchestra and Mezzanine seats to the show that features a "buoyant concoction of bright musical numbers and jokes to please young and old alike" (San Francisco Chronicle) are a surprising $49.50 (regularly $80-$99).

"Shrek The Musical," based on the Oscar-winning DreamWorks film, brings the story of the fabled ogre to life on stage. In a fairytale twist, an unseemly ogre -- not a handsome prince -- shows up to rescue a princess. Other fairytale characters include a persistent donkey, a short-tempered villain and over a dozen other misfits. "Shrek The Musical" also features a score of 19 all-new songs, comedy, dancing and vivid scenery.

Travelzoo Tip: Fees of $10 per ticket and $5 per order will apply. To waive fees, go to the Orpheum Theatre at 1192 Market St. to book in person with the code 3Shrek. The box office is open Monday, noon -6 p.m.; Tuesday-Saturday noon - 8:30 p.m.; and Sunday, noon - 4 p.m.
