According the official release:
It’ll be “all hands on deck” as park guests take on the role of pirates and enter Festival Arena to “set sail” for high adventure with Captain Jack and many of the new Pirate stars in the unique, immersive 3D film experience, featuring a scene from the new movie. Look for “Pirates of the Caribbean: On Stranger Tides – Sneak Peek” on weekend nights from March 25 to May 30, and seven nights a week from April 15 through May 1.
What say you? Will you brave the crowds and weird AP's to get a longer glimpse of POC:OST with a live show?
You can catch the 'Pirates of the Caribbean: On Stranger Tides - Sneak Peek' only at Disneyland from March 25 - May 30.
