Here are my pictures from the Emerald, there are some of the Sanctuary in them. They charge you for half days in the Sanctuary, and I believe it was $10/pp. They don't charge you just to walk around or take pictures there. It's not very crowded at all. It's a place that you can go and relax without people running around, no microphones or games, just a nice quiet area. You can arrange for a massage, they will serve you food, it you want. They will bring you beverages. There is a magnificent view from there. It was one of my favorite spots on the Emerald. Best wishes for a fantastic cruise!
