Disney Cruise Gratuities Posted on July 29th
When booking your Disney Cruise, many things are included in the price. All of your food and non-alcoholic drinks, all the kids club activities, and all adult activities and shows are included. The items not included are usually outlined by your
travel agent of Disney Cruise. Airfare, airport transfers and
trip insurance are usually not included, but are an options that are given you with prices, you can take them or leave them, depending on your plans.
One item that is rarely included, and even less understood is gratuities. On board the ship, there are several people you will become very familiar with, your stateroom steward and your waiter and assistant waiter. Your stateroom steward will take care of your room night and day, he makes sure you have everything you need and that your stateroom is put back together each day. Your waiter and assistant waiter follow you around to each new restaurant each night, and you will get to know them quickly. For these people, as well as the head waiter, much of their salary is based on gratuities from you.
The night before you debark the ship, your steward will place a sheet and a few envelopes in your room with suggested tip amounts for the four people who have served you while on the cruise. The easiest way to pay the gratuities is to go to the guest services desk in the lobby of the ship, and have the gratuities amounts added to your room bill. They will then give you vouchers to put in the envelopes to give to the cast members. You can alternatively put cash in the envelopes. If your service has been great, feel free to add a bit in there. One thing I have done in the past, if the service has been great, is that I have included pre-paid calling cards in the envelopes. Most of the employees on board are from outside the US, and many have families (wife and kids) at home that they support. A pre-paid phone card allows them to call home when at port, and those seem to be more appreciated than equivalent cash for some reason.
Rather than explaining who gets what for each type of cruise, the easiest way to figure out what your gratuities will be is to figure that you will need to pay $11 per person per night of your cruise. So, if you are on a 4 night Disney Cruise, with 2 people, you will be looking at about $88 total for gratuities.
So, while planning your Disney Cruise, make sure you take into account your gratuities on board. If you wish, you can ask your travel agent or the
Disney Cruise Line, and you can pay your gratuities in advance as part of your final payment if you wish.
On board, there are a few other tips you will have to pay. For any room service, while the food and drinks are included in the cost of the cruise, you should tip the waiter that brings the food to your stateroom. Also, any spa treatments that you have done, please remember to tip the employee. If you choose to dine at the adult only restaurant, Palo, there will be a $10 fee per person to eat there, and that is basically the tip for your waiter. Feel free to tip him/her extra if you get great service, but an extra tip is not required.
