Not only are the oceans getting a little more adult these days, so are the world's rivers with the launch of three new river cruise ships setting sail in 2020. TUI River Cruises will debut three ships, the Isla, Maya, and Skyla. Each can only be booked by passengers 18 and over and feature an all-inclusive approach to sailing. With itineraries ranging from the Danube to the Rhine, these vessels will offer a great new way to explore Europe. Now booking, so get out next year's calendar.
