Yes- i heard they dim the lights and stream in the sound. I'm going to work the whole "it's our honeymoon" thing and hopefully get a window at Ohana! From what I hear, the window seats are mainly 2 tops(for 2 people). It won't be as amazing as California Grill (which had me literally crying tears of joy during wishes), but it will be a new experience.
Best of luck to all of us in getting an ADR when they are finally made available!
