Hyatt was first out of the gate with an offer of points for customers having to cancel non-refundable bookings. I thought that was generous because they were first and it was something. Of course this is all fast-moving, and other hotel chains have since done more.
So Hyatt has responded, well I think, and is out with a new policy allowing for cancellation of non-refundable bookings, encouraging new bookings, and offering greater flexibility for Hyatt points.
