[UPDATE, Dec 22, 2017: Hyatt's new "default" cancellation policy, effective January 1, 2018, will require customers of its various brands to cancel at least 48 hours in advance of their planned stays to avoid a fee. "Because each Hyatt hotel may continue to set its own cancellation policy based on local market dynamics and expectations, we always encourage guests to check the cancellation policy at the time of booking," according to the company. For certain elite-level Hyatt loyalty program members, the default cancellation policy is 24 hours, excluding those using pre-paid and nonrefundable rates . . .
