If you'd like to entertain on the world's largest cruise ships, here's some invaluable insider information from one of Royal Caribbean's senior Cruise Directors. We discuss the kinds of acts who work best on ships, why it's not enough to be a great singer, how to won over non English speaking audiences, how long the show should be, socialising with guests onboard, why it's important to have good billing, whether you should make friends with the Cruise Director, how ratings work and whether standing ovations really matter or not.
