I have cruised since 1991 on 8 different cruise lines many times over and over. One thing I always do no matter where I am cruising is research in advance of every cruise. I do research on the ship, the route and the ports. I have been to quite a few places multiple times yet I still do research on those places. You may ask why when I have been there. I do research because things do change. There may be new things to do or see in the ports. The ships do change in various dry docks. The routes may change some of the ports you go to or you may want a new route just to change ports. In other words I suggest you always do research to make every cruise a new experience and to find the best way to spend your time on a cruise. One thing that always changes is the new people I meet on every cruise.
