Cheap Caribbean Cruises All Inclusive

What is the best way to find Caribbean vacation cheap?
My mom and I want a chance to get away for about 5-7 nights. We'd love to do another cruise, but we know it is difficult to find a good market. We also considered all-inclusive resorts, but they are too expensive. Does anyone have any tips on where / what we should go / do? We would like some ideas. Oh! and we expect to travel during the week of Easter, we believe that the weekend will be rather dead (no break, the week / weekend before him). Thank you!
