CheapCruises discounts select 3-, 4-, and 5-Night Cruises with prices starting from $189 per person, as part of its Quick Getaways and Weekend Cruises Sale. (Prices are based on double occupancy.) That yields a very low starting price for cruises in general, although we saw similar fares for $20 less last month. Choose from cruises to the Bahamas; Key West, FL; and more. Additional fees and blackout dates apply. This travel deal ends April 1.
