As it so very clearly says on the Azamara website:
What will Azamara Cruises' gratuity guidelines be?
For your convenience, a gratuity in recognition of outstanding personal service of $12.25 per Guest, per day, will be automatically added to your SM Account. This covers your Butler & Stateroom Attendant as well as all restaurant staff. Since our ships offer multiple open-seating dining venues and you will likely be served by many different staff members during the course of your stay onboard, the restaurant staff allotment is evenly distributed among them.
Guests staying in Penthouse, Royal and Sky suites will experience superior Head Butler service in addition to Butler & Stateroom Attendant service; these guests will be charged an additional gratuity of $4.00 per Guest, per day.
Please note that Bar & Wine personnel are acknowledged with the standard 18% of the beverages and wines billed for the service rendered.
So you cannot remove them and cannot pay who you wish.
