Princess has their plus program which I had first hand experience with for 14 days last year on the Discovery. For an extra 40 bucks per day, you got gratuities, wifi and their drink package. It was so popular they increased the price to 50 per day and after 6-9 months decided to turn it into a two tier system at 60 and 80 per day, with the 60 being the same as the old 40 and 50.
Also, the Celebrity program is not new. Had it on the Celebrity Edge back in January of 2020. Have never sailed on HAL, but I believe they have a similar program.
NCL's perks do not include gratuities, their drinks package doesn't include bottled water or coffee drinks and their wifi only gives 250 minutes.
