Carnival "suggest" to following amounts for each person, including the 10 year old.
$3.50 per day per person...Room Steward
$3.50 per person per day ...Waiter
$2.00 per person per day...@sst. Waiter
Maitre D' and Head waiter is at your desecration. I think this has a lot to do with the amount of attention or work each shows during the week. Many cruisers chose NOT to tip either if all they do is show up the last night and say hello.
On our last cruise I tipped the Maitre D' zero.. I never saw him/her, but tipped the Head waiter more than the waiter. Kelly never charged us a corkage fee, but brought glasses and champagne bucket when necessary, was there EVERY evening helping with the table, joking, and even giving some of us old codgers kisses !! She prepared cherries jubilee, and served our table. So it really all depends on the service offered
As far as the Camp Carnival personnel, I thin a lot depends on how much it is used. I have read where many people tip around $ 25.00 per child for the week.
