I’m loyal to my wife , as for a cruise line ,not so much . I have 20 something Carnival and 20 something Royal cruises under my belt . Soon will have 7 Celebrity . We have 3 NCL , now have 3 Princesses booked. I head where the itineraries are fun and ships look fun and not too big . Mid size range . Then I look at price . Getting too old to worry about anything else .
