Traveling solo can be an incredibly rewarding experience, but oftentimes it comes at a big cost. Solo passengers often have to pay single supplements, meaning that they usually must dole out what a couple would pay for the same stateroom. On October 26th, 2022, I will be hosting solo only river cruise with Emma Cakmak from A Passport To Travel. This eight-night sailing on the Rhine and Moselle rivers is the perfect opportunity for solo travelers looking to avoid paying a single supplement. Prices start at US$3,639 per person.
