Update: A few select rates are still available as of 4:25 Pacific. These rates are also available via Amex Fine Hotels & Resorts if you have a Platinum card which will get you a $100 spa credit, free breakfast for 2, late checkout and more. See the comments for the latest.
This is just a really quick Deal. For certain nights in 2017 the Four Seasons in Palo Alto (Silicon Valley) is pricing rooms at $35 per night plus tax. Rates are cancelable and bookable directly on the Four Seasons website or via OTAs. Search for 1 adult.
