FWIW, just to report back, I ended up in my original throne seat of 12K. When it came to sleeping, I was able to knock out for 7-8 hours after a few glasses of champagne and a sleep aid pill. With that said, I'm a side and tummy sleeper (aka regular "back" sleeping doesn't work for me at all), and if I hadn't taken a sleep aid and had a few glasses of champagne, I would've really struggled to sleep here. The throne seats have very narrow footwells ... you really cannot move your feet much if at all (and I'm not a big guy at all, am 5' 5" in height).
