I have to tell you about my experience with the surveys. We were recently on a ship that we had travelled several times before and saw the guy who had been our asst. waiter and who was now a waiter. He rushed over to say hello and see if we needed anything even though we were not at his table and all the waiters and asst. waiters in the vicinity of our table went out of their way to be really nice to us the entire 15 day trip. We were told by the Waiter that istwas because of OUR glowing comments about him on our survey that he got promoted! We really felt good about it.
(Of course, we don't always have only good things to report on the surveys.)
