Will there be religious services onboard the Ultimate World Cruise and the four Ultimate Cruise segments (i.e., weekly mass)?

While we do try to book priests for our Christmas and Easter sailings, we are not able to guarantee that a priest is onboard for all of our sailings. We will try to book a Rabbi onboard for Jewish high holidays (Hanukkah and Passover), and in the absence of a Rabbi booked by Royal Caribbean International, the ship will ask for volunteers to conduct the Seder service on the first night of Passover. We will also offer special dinners for Christmas, Hanukkah, and Passover.
