Hi Cheadle,
We usually tip the cabin steward $10. Per day in addition to the prepaid crew appreciation. There was one time in our 16 cruises where our cabin steward was basically terrible ( not an HAL cruise ) needless to say there was no additional gratuity from us.
Finally , I have been told that some Doritos or Cheetos are pretty popular among the crew , so if you can safely pack a couple small bags with you for them , I think that would be much appreciated. Needless to say , these extras are all optional and very much up to your discretion.
Hope you have a great cruise 🚢🍀
