See many places and only unpack once.
You can cruise just about anywhere there is water to cruise. My own experience is Caribbean cruises on Carnival on a mid size ships. I got to visit many places on an European cruise aboard the Majestic Princess departing Rome and ending in Dubai. I sailed both the Virgin Voyages adults only ships in Europe round trip Barcelona and Back 2 back from Athens. My inaugural cruise on the NCL Bliss allowed me to experience some of the newest cruise ship additions along the Pacific Coast. We sailed the Celebrity Solstice round trip from Seattle to Alaska. My oldest son and I sailed the smaller Safari Expedition with UnCruise in Hawaii. Along with personal sailings I have specialist training with most cruise line options small, medium and Large.
