DCL:
Help! I'm really confused about tipping!
We'll make it easy. Of course, you should never feel that a reward is automatically expected from you. But it is customary to give gratuities in recognition of service, which you will most likely be treated to in abundance aboard the ship. As a guideline, may we suggest the following:
Per Guest per cruise 7-Night
Dining Room Server 25.75
Dining Room Asst. Server 18.75
Dining Room Head Server 6.50
Stateroom Host/Hostess 25.25
Dining Manager Your Discretion
Room Service Your Discretion
For your convenience, a 15% gratuity is automatically added to bar, beverage, wine, and deck service tabs. All gratuities can be charged to your room charge.
Enjoy your cruise!
