Hi Again Dawn....I don't know what you are referring to about extras, but there are 2-formal nights on the Navigator. They have several different locations with different backgrounds for picture taking. Just take your pick. There is no obligation to buy any of the photos taken on the ship, so if for some reason a photo didn't turn out the way you expected, you don't have to pay for it. I think that's why it is good they have two formal nights. Just in case you need another photo taken, or want two photos with two different backgrounds.
