Planning a cruise on a budget often involves searching for the best cruise deals and specials. While it's true that one of the best ways to save on cruises is to choose major lines' seasonal promotional offers, there are other ways to significantly reduce the cost of your trip. You might even be able to enjoy a cruise on as little as $100 a day.

We consulted with Colleen McDaniel, senior executive editor of Cruise Critic, to get even more money-saving tips. Read on to discover how you can enjoy cruises for cheap.

Purchase an all-inclusive package

An easy way to rack up(增加) a high cruise bill is by taking advantage of every extra that a cruise line has to offer without knowing which extras are included in the package you've purchased. If you're worried about spending too much on activities, beverages, food and accommodations, book an all-inclusive package, which could help you save money in the long run.

Seek unadvertised discounts

Though they don't always advertise them, many cruise lines offer special prices for certain groups. Royal Caribbean, for example, extends special pricing on all cruises to airline employees.

Call the cruise line to find out if it offers discounts for any groups, employers or organizations you are affiliated with, and you could save up to S100 or more a day on your booking.

Use an app to track prices

If you can be flexible with your travel dates, you might be able to get a great deal on a cruise by using an app like Cruise Critic. The app lets you monitor prices of upcoming cruises and informs you of any major changes on prices as the days go by. If the price on your cruise drops after you've booked, you can contact the cruise line to negotiate the difference. The cruise line might refund you in the form of an onboard credit that you can use for cruise activities and other amenities during your trip.

Look for local deals

Many cruise-goers extend their vacations by booking stays and planning activities in port cities before and after the cruise. If this is your plan, save money on dining and adventures by looking for local deals ahead of time.
