Probably a mistake since everything else is showing $119. I am not planning to go so did not actually book, but it does seem to take you all the way to the booking screen (where credit card numbers are prompted).
This is a brand new hotel, and is what they call Napa Valley’s First Fully Environmentally-Sustainable Hotel.
Can book directly from

and specify dates for this weekend. Extended Queen is at the bottom of all the selections.
