They have cut back on the midnight buffets and only offer 1 or 2. In its place are the midnight snacks that are available i the casino and some of the lounges. Actually, it is no loss, as it was simply too much food in my opinion.
I agree with Tom, from my perspective the midnight buffets were a tremendous waste of man power and food. Theme late night deck parties have replaced the midnight buffets, with the exception of one Gala Grand Buffet - usually on the last formal night. If there is no theme party or Grand Buffet, food is plentiful in other venues 24/7.
