Last minute cruises are those that depart within 30 days. As the departure date nears, the cruise line might cut prices to fill remaining staterooms.
To take advantage of last-minute deals, you have to be flexible and take advantage of what comes your way. You may not get your first choice of destination. You may not get the category of stateroom that you prefer.
Be prepared. Keep your passport up to date so you're ready to go if you locate a good deal.
Check cruise prices frequently. You never know when the price may fall and you have to be ready to pounce.
