7 Night Danube – Vienna & Budapest

Celebrity Boundless takes river cruising into new territory, pairing next-generation engineering with a design philosophy centered on freedom and flow. Expansive indoor–outdoor lounges dissolve the boundary between ship and shore, while our hybrid-assisted propulsion keeps each journey quiet, smooth, and remarkably calm. Thoughtful spaces invite you to wander, pause, or settle in as the world drifts by, from our signature cantilevered dining pods to open-air terraces created for conversation and connection. Here, every part of the ship is an invitation to explore your way, in your time.
