According to the OC Register:
Not really good news in my opinion. If they’re not going to start construction until next year, then they should just keep the attraction open to everyone. Just my 2 cents…The last performance of Golden Dreams for the public, an American dream film performance in Disney’s California Adventure, is Sept. 7. Disney announced back in fall that as part of sprucing up California Adventure, Golden Dreams will be replaced by a dark ride based on “The Little Mermaid.” So, if you want to see the show — show up by Sept. 7. Still, the theater will be open through the spring, but only to school kids as part of the Disney youth education program.
