TRON Lightcycle / Run I’m calling this “unofficial” because I don’t have an official Disney source, but I’ve heard it more than once and I think that it’s accurate information. The Cast Member Preview dates for TRON Lightcycle / Run will be February 3 through March 3. Cast Members will be able to sign up starting on January 30. If the information is correct, that means that Passholder and DVC Previews will most likely start in early March, but after the third. That last part is a guess on my part, based on previous previews. TRON Lightcycle / Run opens to all on April 4.
