If you enjoy solo traveling without sharing a room, then we’d recommend the Rhine, Strasbourg & Heidelberg River Cruise for Solo Travelers. This eight-day cruise starts at $2,449 per person and features eight guided tours, a live classical quartet recital, daily meals, and five-star services. For this particular cruise, you’ll embark in Cologne and visit destinations like the Rhine Gorge and the historic Mainz port. Plus, there are departures aimed at solo travelers specifically, which start at $2,749 per person. Unfortunately, there’s no single supplement, but there are also no additional fees; I paid the listed price, which was a welcome departure from other cruise lines and their many hidden fees., Looking for 10 day senior cruises?
