Okay, so what have I missed here? according to the link you added .....
Each guest 21 years and older may bring one bottle of wine or champagne (no larger than 750ml) onboard in their carry-on luggage at the beginning of the voyage
So as there are 2 of you = the 2 bottles you wanted to take, or are you under 21?
The pre-ordered vodka & champagne wouldn't be included as they will already be on board.
The other interesting note is that HAL "reserves the right to remove all alcoholic beverages from guest luggage that violates this policy. Any alcoholic beverage found will be removed and returned on the last evening of the voyage."
So it doesn't say that they WILL, just that they can, and if they do, they will return it on the last night, so you won't lose the wine.
Sounds to me like it's worth the risk over taking more on board that their policy allows, & hoping.
It would be interesting to know what happens in realisty, most of the UK departures have similar rules, but only ever enforce them if there is a group carrying on excessive alcohol with the plans of getting wrecked & unsociable to the other pax.
