Bruce, again, it is not an "auto-tip." The money is going to NCL. They are saying to "supplement salaries and benefits." Bottom line.. it's going to NCL!!!
If a restaurant (or any business for that matter) raises its charges to pay for salaries or benefits, you wouldn't consider it a tip and not leave anything on the table so I don't know why anyone is considering this a "tip."
NCL is confusing the matter by separating this from the upfront cost of the cruise. That's all. "Auto-tipping" does not exist on freestyle cruises. Tip as you would in any restaurant or hotel.
