We picked the Rhine Getaway over the Danube because the 8-day length felt just right, and one of us had already been to a few Danube cities. Going from Basel to Amsterdam was a great call, and the Lucerne add-on at the beginning was totally worth it—Mt. Pilatus, the lake cruise, and that cable car ride were all awesome. The Explorer Suite worked out really well for two friends traveling together—plenty of room to spread out, unpack, and even enjoy the castle views from our balcony without heading to the top deck. We loved the Black Forest hike, beer tour in Cologne, and the e-bike ride in Kinderdijk, and we’re already thinking about our next Viking cruise.
