Yes, you can effectively "pay your own" gratuity on a Carnival cruise, but the process requires a specific step at the Guest Services desk. By default, Carnival automatically adds a daily gratuity (currently around $16.00 to $18.00 per person, per day) to your Sail & Sign account. If you prefer to tip crew members directly in cash, you must visit Guest Services toward the end of your cruise to have the automatic charges removed or adjusted. However, the cruise line strongly discourages this because the automatic pool ensures that "behind-the-scenes" staff (like laundry workers and kitchen crew) also receive a fair share. If you do choose to pay in cash, keep in mind that many crew members are required to report these tips to their supervisors. Most experienced cruisers choose to leave the automatic gratuities in place to ensure everyone is covered and then give additional cash tips to specific staff members who provided exceptional service, such as their room steward or favorite bartender.
