We’ve never cruised before. I’m just beginning research for a cruise for summer of 2020. My daughter is graduating high school and I always said I’d take her on a cruise for her graduation, just the two of us. To get an idea of available cruises I looked up iteneries on several lines. I didn’t put in dates. I saw several inteneries I liked at first. I would love to try one of the Panama Canal ones that leaves from the west coast and arrives in Florida. I also saw several Carribean ones that included both the west and east. I was wanting a cruise that was between 14-20ish days and stopped in multiple countries. My goal is to see as many different places as we can. Then I started to notice none of these were offered during the summer. When I plugged in May, June, July of 19 (20 wasnt available yet) as a filter none of these longer cruises were listed. Unfortunately we are firm on our dates as she will be graduating high school and then going off to college, we only have the end of May-July. Do all major cruise lines just not operate the longer cruises during those months? Are they just not all listed yet? Do they typically run similar iteneries the same time each year, or could I expect summer 20 to be different than summer 19?
