I am a first time cruiser. I saw a YouTube video where a couple shared I do not need to pay "Pre-pay Gratuity". The couple shared that I can tip as you cruise. For example: I can tip a porter that takes our luggage, I can pay housekeeping each day for cleaning our room, I can tip at the waitress or waiter when he/she serves my family.
Is this correct?
To me that will work best but I need to know.
