Princess Cruises adds new Traditional Dining seating time
Dear Travel Professional,
As part of Princess Cruises’ continuing commitment to service, we’re pleased to announce the addition of a third Traditional Dining seating time on most voyages. The new seating time is in response to the high demand we’ve received for our popular Traditional Dining option, and as the Consummate Host®, we’re happy to accommodate our guests and travel agent partners.
The new seating time will be in a separate dining room at either 5:15 pm or 5:30 pm depending on the voyage. The only voyages not offering the third seating will be on our small ships, or those sailing in Australia.
