Sky service charges

Does anyone know" exactly" what the mandatory service charges are on the 3 day cruise on the Sun either per day or total. Tried calling NCL and was on hold forever. I have read conflicting reports of what is charged to credit card . Also if anyone knows what they put as a CC hold on 3 day cruise. I may have to move some money around before we go so I am very interested. Thanks in advance.

You can also pay the DSC now instead of having it deducted from your on-board account.

It is easier to prepay your service charges so there are no charges onboard.
