I'll just say that if you have to get 24 hours of unrelenting stomach 'flu and if you are unfortunate enough to be away from home, I would recommend the Seattle Renaissance, Suite 2710 as the place to be because when you're eventually able to open your eyes without the room spinning you will have this fantastic view of the city.
And this one, towards Pioneer Square, too.
You can watch the weather roll in from every angle for the next day or so while you recover. Looking across Puget Sound by day
until it's time to leave.
