It's now gone up to $11.00 per day per person.
Just remember that if you opt out of the automatic tipping, anything you give your cabin and dining room stewards will have to go into the "pool", they will not be allowed to keep it. If you stay on the automatic tipping, anything extra you give them, they are allowed to keep.
Please think this over before you opt out even if it's just for the kids.
Also please remember the steward has to make up 3 or 4 beds, clean up the room, remove and replace all the towels, etc. in the bathroom, etc. etc., even if 2 of the persons are children.
