Welcome to Accor! Of course the code in the e-mail did not work on the website. I say again, Welcome to Accor.

Here was the announcement:

"Welcome to the Fairmont Private Sale. Take advantage of exclusive savings of up to 30% off at some of our top destinations around the world. Discover all the share-worthy sights and attractions of a new city, or cross an exotic locale off your bucket list. With savings like these—there’s never been a better time!

Fairmont Private Sale
Book by January 19, 2017"

So, tried to book Boston for 3 nights in February for 20% off - which should be available - but all days in Feb were not available online. I am Accor Platinum and this is not unusual for their private sales not to work.

Called in and it was available. Best part - confirmed that certificates can be combined with this rate - so came out about the same as Great Rates Great Dates - but was able to use a Free Night and a Suite Upgrade.
