"Reuse the scene where the queen is in the bath at the begin of the story"
Sadly, that was the first thing I tried. The way that set is built, I couldn't make the bath bigger without making the floor and everything connected to it larger as well. There just wasn't a good way of making it work.
I'm just writing off the pool lights as some kind of luminescent crystals and the wall lights are just fancy fixtures overtop candle holders.
