Some include wine with dinner, coffees etc only, not 15 alcoholic drinks a day. I have an occasional glass of wine with dinner, and DH doesn’t drink at all so that would suit us.
We like a quieter, more sedate cruise experience anyway and not feeling Princess is really that anymore if they ever were. On our last cruise, I was unable to find a single quiet public room to read my book. Loud music playing in all areas at all times, even in completely empty areas.
