It can be fun to go on a cruise. There are some great last-minute cruise deals. It's possible to get a week in the Caribbean for less than $400 per person.

If you are picky, you may not find an acceptable cruise bargain. Ships, cabins and dates are less likely to be near the top of your list if you wait too long.

Don't expect a deal on the newest ship or the fanciest cabin. Demand is higher than last-minute offers. If you are trying to get something done before the deadline, you should be flexible on when and how long you will travel.

These deals can satisfy the itch when you say, "I want a vacation, NOW," but your pocketbook says otherwise.

Is it a good idea to book a cruise late? If you want to know if a last-minute cruise fare is right for you, here is a primer.

What are last-minute deals and why are they offered?

When a cruise line doesn't sell enough cabins for a particular sailing, last-minute deals can be found. A cruise line might cut fares to fill empty cabins.

After everyone who booked in advance makes their final payment, offers for last-minute cheap cruises can be found.

Cruise lines get a good chunk of their income from onboard spending so they make a bigger profit if they get more people on board. That strategy can go wrong.

More people might be hesitant to take advantage of early-bird offers, and other sales geared to those passengers booking several months in advance, if lines always offer last-minute cruise bargains.

Is it a good time to book a cruise?

Cruises don't always offer last- minute deals. They are targets on a ship-by-ship basis.

How much can I save?

ALL INCLUSIVE PROJECT/CELEBRITY CRUISES

The last-minute deals at vacationstogo.com ranged from about 30% to more than 85% off full fares. It's rare for anyone to pay a full fare.

You should compare the last-minute fare with other offers and perks from the cruise line.

Some lines offer kids-sail-free deals, but they might not apply to some last-minute fares. Booking early will allow you to take advantage of the value-added ways to save.

What are the cancellation policies on last-minute fares?

There is a chance you are booking a non-refundable fare. If you make a full payment at the time of booking, you won't have to put down a deposit.

You have booked a cruise. If you cancel, you'll get less back than you paid, and you won't get anything if you don't sail before 30 days.

Are these fares offered at certain times of the year?

If you keep an eye on the calendar, you can improve your chances of getting a last-minute deal.

Busy periods for Caribbean and Mexican Riviera cruises include any time that kids are out of school for a week or more, such as winter and spring school holiday periods. There will be less last-minute fares during these times.

Some of the best deals are before and after the kids are in school. If you plan to sail later in September through December, you will find last-minute deals.

There is no change for the month after New Year's and into February. Keeping track of the other pockets is important.

There's a way to get a deal on a cruise ship.

The shoulder season is when to look for deals in Europe and Alaska. Peak season in the summer is late in the spring through August.

It's important that flexibility is present. You are more likely to find a last-minute deal if you search for an available period of several weeks or even no set time in mind for your cruise, instead of targeting a specific date.

Are there more last-minute deals on specific itineraries?

I agree. There are last-minute deals on cruises that are shorter than a week or on cruises of more than 10 days. Repositioning cruises include voyages between Europe and the Caribbean.

It is possible to get a last-minute fare on a popular seven-day sailing in the Caribbean, Mexican Riviera or the Mediterranean.

What sort of cabins are offered last minute?

PRINCESS CRUISES

The problem is there. You have to be flexible in this case. The last-minute fares may not be for all cabins.

The cheapest cabins tend to sell out first, so don't expect these accommodations to be available. If you are on a route like Alaska, where everyone wants a balcony cabin with a view, don't expect many of those to be available, either. There are cabin types that are limited in number.

You should be prepared to take the type of cabin and the location. It is possible that the last-minute deal is for a guaranteed cabin, which means you don't choose your cabin at all.

You could get a better cabin than you paid for, but you could also get a cabin that was avoided by earlier bookers.

How close to sailing can I book?

You can book just hours before a cruise, but you can't book after the ship's manifest has been submitted to authorities The last day to book is one to two days before the cruise.

If you wait until the last minute, you may not be able to book online or call the reservations line.

Should I book a last-minute cruise if I have to fly?

The airlines could take the savings from cheap last-minute cruises. It's difficult to find last-minute airfare deals. If you can save by booking your flight through your cruise line, you should do it.

If you want to save money, last-minute cruises might be the best option. People who live in Florida or winter in the state can take advantage of last-minute deals because there are many major cruise departure ports within driving distance.

Will I still have access to shore excursions and drink packages?

ALL INCLUSIVE PROJECT/CELEBRITY CRUISES

You may have to be okay with taking what is left. The most popular shore excursions are likely to be sold out if you book a last-minute fare. The opportunity to pre-book spa treatments and specialty dining at popular times is limited in number.

Do I need a passport?

Make sure your documentation is up to date if you're looking for a last-minute deal on a route that requires a passport. It can take months for renewal to happen before a cruise.

Bottom line

Even though you can get a last-minute deal for a cruise, it doesn't mean you should. If you can drive to a departure port, then go for it. It's often just what you need.
