Both Carnval and RCCL have the exact same options for tipping. This is from the RCCL website:
Pre paid by having them added to your reservation by your booking agent.
Added to your onboard SeaPass account.
Paid in cash at the end of the cruise
A couple of questions, Joe,
Both Carnival and RCCL automatically add a 15% gratuity to bar bills. Do you tip differently if you go up to the bar and order a drink or if you are sitting down somewhere and a waiter brings you a drink?
When you order room service on either cruise line, do you or would you tip the person that brings it to you?
