Under the Sea: Journey of the Little Mermaid is not listed on the calendar beginning on February 2, 2015. Other attractions have times through February 28th. WDWMagic.com user lnsemsf has reported that the attraction is expected to be closed from February 2nd – March 6th.
Last year, the Little Mermaid attraction at Disney California Adventure underwent a significant refurbishment where static fish props were added and the interior props and animatronics were repainted with black light paint. The attraction underwent lighting changes as well to enhance the blacklight paint. The same changes have been rumored to be taking place at the Florida version of this attraction.
