I think I read on wdwmagic.com that it reopens on 11/30...I hope so, we arrive on 11/29 and that is one thing my DH really wants to see. He loves ANYTHING to do with the ocean.
Just so everyone knows - Rumor is that only a portion of The Living Seas will be reopened in November. The whole SeaBase Alpha area will be what is open (Turtle Talk, the aquarium, etc). The old queue area, the movie area, and the hydrolator area will remain closed. Supposedly, the above may be replaced by a Nemo ride and/or Nemo movie. This section of Living Seas will not be open until sometime in 2006.
Disney's been pretty tight-lipped about this project so no one really knows what's going on.
