Just to clarify - the Galley tour we attended on the 7-night Fantasy (in June, 2013) was never advertised as an offering in the navigator. You had to know enough to ask. I had read about it on the Disboards, so I made a note to ask the Concierge Team, and they signed us up. However, it was not only concierge guests, so I imagine you could inquire at Guest Services just as you would any ticketed event. It was adults only, free of charge, and they told us where and when to meet. It was on a sea day and yes, it was between food services, so there was hardly anyone in there, other than perhaps someone prepping salads, but we still found it interesting because we had a mental picture in our head from then on about what goes into feeding so many massive amounts of people. It was also kind of cool to see their schedule printed out, so they didn't get mixed up about what kinds of food were on the menu for a particular evening - LOL!
