There is a saying that everyone should try a cruise once. Short cruises are cheaper. 3 to 5 days. Some though can e party cruises. Most likely the shorter of that over the weekend ones. End of August to February or so lower prices except over Thanksgiving, before Christmas to over New Years. The weather on a Bahamas/Caribe cruise will be warm there and the seas having a greater chance to e calmer. If you talk to a cruise rep on the phone, if they are cruisers, they will talk a long time with you Ask questions to comfort you. Know what is included, what costs extra and be careful about nickel and diming. If you are worried and want travel insurance, ask but know that the cruise line will charge more for it and there are reputable cheaper outside insurers. Same with ship excursions if you choose to.
