I describe Princess as sophisticated casual. Celebrity is edgy and "hip."
I think the "cool kids" sail on Celebrity. Going on a Princess cruise, to me, is like going to our lake cabin - it's comfortable, I know where everything is, and I'm surrounded by people who share interests with me.
I just prefer Princess, and I think the fares are a good value. We have taken the Plus or Premier package almost every time since the restart. We usually have a couple of glasses of wine with dinner and another cocktail before the show. That's enough for us to see value in the packages. We like the casual meals at Vines and Alfredo's.
