Want to experience cruise travel, which one is better, ocean or inland river?

European and American river ships are very different from ocean cruise ships. After the Industrial Revolution, the Age of Navigation emerged in Europe, and river cruises became a symbol of European royal aristocrat status. You could spend time leisurely while drinking champagne, basking in the sun on the deck, and looking at the scenery on both sides of the river. It has evolved to this day, and top-level river cruises have become an emerging fashionable way of travel, and it is a relatively more private trip! Compared to large-scale ocean cruises, traveling on a river cruise is more niche and private. And you can dock anywhere, and you can play on the shore without having to travel to your destination, which is very convenient. For example, I have experienced the high-end cruise ship Viking Cruises before, with exquisite meals, smooth water flow, beautiful scenery along the way, and numerous advantages.
