We sailed on NCL Spirit, from Barcelona, on Oct 26, 2013 ... with my wife Heidi and daughter Lori + her husband, Jay. It's a beautiful small ship. You can go everywhere with ease yet there are lots of open, uncrowded spaces ... and there's always something happening, somewhere. Lori & Jay did some exercise thingy and trivia games, Heidi and I watched some fruit-carving, cake-making, towel-folding demos.
Before the cruise, we stayed for three days in Arturo's apartment, Barcelona.
