I am deciding between the park hyatt and the langham, will be booking through amex fhr so I'll receive the same benefits with either hotel (though I will lose out on the diamond amenity at the park hyatt, assuming those are still given in January ). The park hyatt is currently $100 more a night and I would have booked it before World of Hyatt was announced but I am now strongly leaning towards the langham. Any suggestion either way?
