Which cruise line excursions should you take, and which not? I suggest 6 excursions that I would usually take with the cruise line, rather than with an independent tour company or self tour. I also recommend 6 that I would suggest you consider not doing with the cruise line, and how to do them yourself. The big advantage of going on a cruise line excursion is the ship will always wait for all their tours to return before leaving. They do not guarantee to wait fro late passengers on their own arrangements. However, consider my list of ones to do and not do when planning excursions on your cruise vacation.
