This was my 8th Carnival cruise. Let's set aside how ridiculous it is that Carnival changed their smoking policy after many of us had already paid for our balcony rooms.
The coffee and drink machines, with the exception of two, were turned off as soon as the buffets were closed. Therefore, you had to walk quite a bit to find a drink. When they were all turned off many of them didn't work. That was for the whole cruise. They ice cream machines were much the same.
The food on the buffet has changed so much since the new CEO took over. I'm not sure why Carnival thought that a man that was in the Roundup division of Monsanto would be a great CEO for a cruise line. I usually just ate a hot dog, hamburger, or grilled ham and cheese.
