Fairmont is now offering a buy-one-get-one-free promotion: book one night at any of the hotels listed below and you can get the second night free. Be sure to book before the deadline specified by the promotion. I took a look, and it seems this really is a genuine stay-one-night-get-one-night-free rate, without any price increase baked in.
Looking through the list, there are 9 participating properties in the U.S., 12 in Canada, and 2 in Mexico.
Our writers have also stayed at quite a few Fairmont hotels, and the reviews have generally been positive. Many of their properties have a certain sense of history and come with stories of their own. If you prefer newer hotels, though, this may not be the best fit for you.
