Decide on the budget for your cruise. This will help you narrow down your choices when presented with last minute cruise deals. Be sure to factor airfare into your budget.
Log on to the Internet and navigate to a travel site specializing in last minute travel or budget cruise vacations (see References below for several options). Some sites (like Lastminutetravel.com) provide options to search for discounts based on your state or age. Check these options to expand the possibilities for budget cruises.
Browse the "Featured Specials," or select a specific destination from the drop-down menu, and a specific date range (if applicable), and select "Search."
Choose your cruise from the search results, keeping your budget (and desired destinations) in mind. Book directly on the website.
Navigate to Ebay.com, Craigslist.com, or another cruise auction site (see References below) for further last minute cruise deals if you are unable to find your desired cruise option on any of the last minute travel websites. Search for "Cruises" and bid on cruise tickets sold by travelers unable to use their tickets.
