While river cruises and ocean cruises share a number of similarities, there are also various â€” and considerable â€” differences between the two. The ships for ocean cruises are generally more substantial than those used for river cruises, and have more features in the individual rooms. Many additional travelers can travel on them because of larger size. Since river ships hold fewer travelers, passengers tend to get to know each other better and oftentimes create long-term friendships. Another significant difference is that river cruises generally do not ever travel a full day, as opposed to ocean cruises which might be at sea for many days at a time. Each day delivers you to a different port of call. The view is always shifting, so the ride itself is part of the exploration. If you are concerned you might get seasick, a river cruise is the way to go, because land is always visible nearby, the water is not deep, and the sailing is ordinarily without any turbulence. Yes, ocean cruises tend to offer other upscale features like fitness centers, numerous dining options and a wide see route array of live entertainment. But river cruises are great in that they give you inclusive pricing that covers water, alcoholic beverages, Wi-Fi, and even some fun adventures off the ship.
