Here is a brief description of 21 types of cruise discounts that are currently available to savvy consumers.

1.  2-for-l's - or second passenger cruise free: This is one of the best cruise discounts currently available to consumers. 2-for-l's are offered on a consistent but selective basis by many cruise lines including: Princess, Celebrity, Costa and Holland America. Carnival, Norwegian Cruise Line and Royal Caribbean do not typically advertise 2-for-l's, but their promotional pricing can be equivalent to a 2-for-1 discount. Generally, 2-for-l's are for the cruise only, but on rare occasions they include air from select cities.

Princess has more 2-for-l's than any other line but they are usually regional offers so the cruise agency must be informed enough to know where the deals are. These offers are capacity controlled and may be withdrawn without notice. They are often offered on a "last minute" basis, 30-60 days prior to a sailing. However, for longer or more exotic sailings, 2-for-l's are sometimes available up to a year in advance.

2.  Better than 2-for-l: What could be better than 2-for-l? 2-For-1 plus an additional $500 off per person. This is promotion is often used by Holland America and Princess.

3.  Added value: This may include offers like; "Book a 14-day cruise and get 7 days free." Other offers may include free shore excursions or a free pre- or post-cruise hotel room. One cruise line offers a free 35mm camera, a $700 value, if passengers sailed on a specific sailing date. Commonly used by Holland America, Norwegian Cruise Line, Costa and Orient Lines.

4.  Flat rate specials: Flat rate specials usually give one fixed price for the best available cabin at the time of booking. There is usually one flat rate for inside cabins and one for outside cabins. The offers are usually for the cruise only, but airfare may be purchased for an additional price. Commonly used by Princess and Norwegian Cruise Line.

5.  50% - 80% off the second passenger: This is a nice sounding way for a cruise line to offer a 25%-35% per person discount for a specific sailing. There is usually an expiration date to these offers. Commonly used Holland America, Cunard and Costa.

6.  Reduced rate or free air add-ons: Air add-on rates are offered by many cruise lines in conjunction with their cruise only rates. Sometimes, special pro-motions are offered where the air is reduced. For example, an air rate of $299 from Chicago to Miami may be reduced to $149 or $99 per person. In some cases, a promotion may be featured in which the quoted air add-on rate is waived and offered free. Commonly used by Oceania, Royal Caribbean, Celebrity, Norwegian Cruise Line and Holland America.

7.  Senior Citizen Rates: Reduced rates for seniors on select sailings is commonly used by Royal Caribbean, Celebrity, Costa and Norwegian Cruise Line. One passenger in the cabin must be at least 55 years old to receive the discounts.

8.  Free pre-cruise Hotel Stays: This is a common "added value" on deluxe and luxury cruise departures in Europe and Asia. This is commonly used by Regent Seven Seas and others. .

9.  Repositioning cruises: A change of itinerary is common with many cruise lines, particularly with ships that reposition from the Caribbean to Europe or Alaska and back again each season. Some repositioning cruises are deeply discounted with 2-for-1 savings.

10.  Free upgrades: Popular with Norwegian Cruise Line, Carnival, Celebrity and Royal Caribbean. Most of these upgrades are unadvertised and may be withdrawn without notice.

13.  Discounts for combination or back to back cruises: Used by Cunard, Holland America, and Orient Lines. Book one week and get the second week for a reduced rate.

14.  3rd/4th passengers cruise for a reduced rate: 3rd/4th passengers traveling in the same stateroom qualify for a reduced rate on cruise lines such as Carnival, Celebrity, Costa, Norwegian Cruise Line and Royal Caribbean.

15.  Group discounts: A) Companies like ours have reserved group space on a large number of sailings to destinations around the world. By linking onto these sailings, individual cruise passengers can take advantage of rates that are normally afforded only to those traveling in a group. B) Affinity groups that travel together such as family reunions, religious groups, clubs/associations, corporate/incentive meetings, etc. receive group discounts as well as he free berths, depending on the number of passengers.

16.  Stand-By-Rates: Holland America, Princess, Crystal and Cunard have used Stand-By rates. They usually require payment in full with confirmation three weeks prior to sailing. If the stand-by does not clear, a full refund is given. This type of promotion less common.
