difference between free open bar and unlimited open bar - NCL

[sully108]

Is there a difference between free open bar and unlimited open bar on board an NCL ship ? 

I see then using 2 different phrases when I am on their booking site. What is the difference IF there is a difference ?

No difference. The sky and sun sailings where everybody gets drinks included are different (less selection included).

The Free Open Bar on Sun and Sky does not include premium alcohol nor bottled water or premium coffee. 

 

The drink package under the Free at Sea promotion includes these items and you pay the 18% on the package.

The UBP does not cover bottled water nor premium coffee.

The drinks package under Free at Sea promotion does *NOT* include premium alcohol, bottled water, or premium coffee.

The "open bar ends on both ship at the end of the month or possibly a Sept 2nd or 5th sailing for Sun. Aug 31st sailing is last for Sky. A shame as it was great to just walk up and order, no card, slip of paper back...

So now the Free at Sea includes Unlimited Open Bar vs the UBP - I have looked and I don't see the differences between the two, I know with UBP or whatever they are now calling it has a limit of $15.  Is there a similar limit on the Unlimited Open bar?  I somehow feel like this is all a shell game
