On my first cruise, My wife and I had a ball on RCCL (Sovreign of the Seas) about 13 years ago. Our cruise charge bill was 4 and one half pages long, and worth every penny.
When we cruised the Mediterranean a few years ago (Greek Islands, Rome, Turkey), it was more moderate, as we don't drink as much anymore. Only two pages.
But remember where you are when considering prices. If you were at a NICE bar in Miami. San Francisco/London/New York, $4 for an import would be a steal, and you would likely leave a $5 to include the tip.
In the USA Today article they said the $54/night was a bit misleading as the room was $108/night since they had two people. I guess the value of 3 all you can eat meals at nice restaurants was free, in their minds.
I expect my food, lodging and general activities to be inclusive, but I Expect to pay for my excurisons, Alcohol, pictures, etc. In fact, I don't want a one price fits all since if I don't use a service I don't want to pay for it.
IMHO.
