I am not an "old time" cruiser, our first cruise was in 2004, so I admittedly speak from ignorance of the glory days of when the food was better. I do have to wonder if this supposed decline in food quality has to do more with the ever increasing size of main line cruise ships than any other factor. It must be incredibly difficult to serve 1000 high quality meals at approximately the same time.
