Tipping porters at the cruise terminal are not required, but it is expected. It's best to have some small bills ready when you approach the drop-off zone in the cruise terminal so that you can tip each bag carrier that takes your luggage.  The standard amount for tips varies anywhere from $1 to $5 per bag carried, and many passengers find that going a little higher than this will be much appreciated by the porters. Being prepared with enough cash can make all the difference as sometimes lines can get long, and having enough money on hand will make your departure smoother.
