Once you've decided to take the plunge and book a cruise vacation, how do you know you're going to get the best value for your dollar? One of the first things to do, is decide on at least the type of cruise you want to take, for instance the Mexican Riviera or the Caribbean. Choose the length of your cruise, and what you must have for accommodations, entertainment, shore excursions, etc. and then make a second list of things you would like to have but can sacrifice if necessary. Then you can start looking for the best bargains in cruise packages, and investigating travel agencies online or locally, who offer discounts.

For example, you may decide to do a seven-day trip to the Bahamas, and want lots of onboard entertainment options, as well as interesting ports of call with a variety of shore excursions that appeal to everyone in the family. The prices you find for longer cruises, may be higher than you anticipated, but taking an inside stateroom with a sofa bed could save you the money that makes it balance out to the same rate as a shorter cruise in different accommodations.

With your lists in hand, surf the cruise lines' internet websites, and see which line comes closest to filling all your requirements. Write down their prices for two or three accommodation options, as well as any extras offered that you hadn't thought of. You can then contact the company for a quote on the cruise you have in mind.

From there, you can start checking out agents who advertise specials, cruise packages and discounts. Be wary though- the discounts or savings may take the place of some essential part of what you really wanted, such as child care services, or a variety of evening entertainment. The ship on which their booking is offered, may also depart from a port that is further away than anticipated.

Once you have done your browsing and are clear on what each agency or cruise line is offering, take all your prices, your personal lists, and decide which suits your budget, and which will deliver the vacation that you've dreamed of.
