Yes I see the "Pay My Way" - popup allowing mix of rate, points, point+Cash, Awards, for regular Hyatt owned hotels, but just doesn't work with MGM properties. But good know this for future bookings at Hyatt owned properties.
Try reaching out to them on twitter. I've never had an issue using two certs back to back on one booking.
