For a Disney Cruise Line vacation, you have the option to prepay your gratuities at almost any point from the moment you book until a few days before your sail date. Specifically, you can add prepaid gratuities to your reservation online through the "My Reservations" section of the Disney Cruise Line website or via the mobile app up to 3 days prior to embarkation. If you booked through a travel agent, they can also add these for you. Prepaying covers the suggested tips for your Dining Room Server, Assistant Server, Head Server, and Stateroom Host, which currently totals approximately $14.50 to $15.50 per person per night depending on the cabin category. If you choose not to prepay, the standard amount will be automatically charged to your onboard account on a daily basis. Prepaying is highly recommended for many travelers as it helps in budgeting for the total cost of the cruise before ever leaving home. It is important to note that you can still adjust these amounts (either up or down) once you are on the ship by visiting the Guest Services desk, and gratuities for spa services or bar drinks are automatically added as a 18% service charge at the time of purchase.
