Cruise Cheap, a cruise consolidator, has a drop-down menu or singles cruises on its cruise search banner. If you give your email address, they will notify you of hot deals by email. The site also offers promotions, like a $500 on-board credit when you pay with your American Express card.
Cruises Only has a weekly newsletter that offers last-minute discounts of up to 80 percent off. The site has a Facebook page where you can get early notification of deals. Cruises Only also offers information for singles on gay-friendly cruises.
Vacations to Go has two ways to search for bargains. The "90 day ticker" offers last-minute cruises, while "find a bargain" has a longer lead time, with promotions like two for one, where you can bring a single friend. A singles cruise specialist can help with finding a roommate to avoid a single supplement, and the e-newsletter offers weekly bargains.
SinglesCruise.com has singles events on board different cruise lines, with get-togethers, lectures, a dining area and excursions specifically for the single traveler. Sign up for the weekly e-newsletter to receive information about special offers.
