I had a booking earlier this week at the Sheraton Seattle. Before my stay, I received a rather intriguing email from the hotel. This email included included a “say when…a 24 hour experience.” Similar to the service that is offered at the Beverly Hills Peninsula, this email suggested that I could arrive any time I wanted (including outside of “normal hotel hours,”) and stay for 24 hours from the time of arrival. I have a more detailed post here. Not sure if this is a trial or something frequently offered at this hotel. I've not seen it mentioned before. If offered consistently, it would be a nice reason to select the Sheraton.
