Congrats on your first cruise and to Hawaii... that is GREAT !!!
$10.50 per day per passenger is the auto gratuity guideline charged to your portfolio and will be split amongst the staff that are taking care of you.
When you see how hard the staff are going to work to please you and make your cruise enjoyable, you will realize that they have earned the auto tips. I hope that they impress you enough to EARN a gratuity "Bonus" for anything they do that exceeds your expectations !
Have a GREAT 1st cruise and please report back to us with a review of your cruise when you return !
