Cruising is often associated with alcohol.

Whether cruise lines are creating select wine menus to match the various regions they sail through or if they’re introducing new lounges and bars to create a funky nightlife – alcohol is a big part of cruising, and it can often be quite expensive.

There are a few sites in the world wide web that provide tips to help cut the cost of on board alcohol expenditure, but there’s nothing cheaper than bringing your own liquor.

Unfortunately, on most cruises passengers are restricted from BYO alcohol.

Yes, cruise lines are quite pedantic when it comes to bringing your own alcohol on board, but there is the exception of four lines that have loosened their policies.

1. P&O Cruises UK lets passengers bring alcohol on board with them. According to Cruise Critic, there is no exception to the amount that can brought onto the ship, however P&O does reserve the right to remove alcohol at embarkation if the need arises.

Unfortunately for Aussie cruisers, this except does not apply to P&O Australia – guests are not permitted to bring any alcohol on board for personal consumption.

2. Disney Cruise Line lets passengers 21 and over bring beer and other types of liquor on board. The liquor can only be consumed in-cabin. Despite this flexibility, Disney still holds alcohol purchases at the duty-free shop until the last night of the cruise.

3. Azamara Club Cruises allows its passengers to bring liquor on board. However, just like Disney, the alcohol must be consumed in-cabin, otherwise passengers can pay a $10 corkage fee for consumption of personal alcohol outside the cabin.

4. Princess Cruises in Australia allows passengers to bring on 750ml bottle of wine or champagne per voyage. There is no corkage fee if the alcohol is consumed in a stateroom.

Princess Cruises’ website says: “Additional wine or champagne bottles are welcome, but will incur a $15 corkage fee each, irrespective of where they are intended to be consumed. Liquor, spirits, or beers are not permitted.”
