NCL: The service charges of $10 per adult per day ($5 per kid) are automatically added and are divided among a pool of crew members.
Carnival: On the first night of the voyage, guests receive a letter explaining the distribution of the suggested tip amounts ($10 per person per day divided between cabin steward, dining room staff, etc.) and are made aware of what amount goes to whom. They are also advised that they have discretion as to the amounts and the distribution of the tips themselves.
I think
DCL works out to about $12 per person per day on a 7 day cruise.
We're already paying more for a
Disney cruise than other cruise lines... and then we're asked to tip the staff more than the other cruise lines.
I tip according to the level of service. If Disney's recommendations were mandatory, their recommendd tipping amounts would already be on our bill. Because they are not mandatory, the staff has to earn their tip. Just like in the parks .... when we're asked... "are you on the dining plan?"... we saw a difference when on the dining plan... the servers relaxed and weren't as attentive because they knew they'd be getting the 18% tip no matter what. We had better service without the dining plan because they had to earn their tips.
