I was able to talk with the crew on the MerMaiden of Scarlet back in October. They said it all comes down to Richard Branson's philosophy: take care of the crew and they'll take care of your guests. And it shows. Besides the free internet, more casual dress, and everything that has been mentioned already, they also have shorter shifts with breaks in between instead of long shifts. They truly feel like they're being looked after. And it's the little things too, like not having to cover up tattoos or piercings.
