Save on extensions in Budapest, Vienna, Porto and more.
Don’t let the adventure end too soon. With 50% off selected river cruise extensions, you can add extra nights in hand-picked hotels and soak up even more of the sights.
Picture yourself wandering Vienna's grand boulevards, sipping coffee in Budapest's historic cafes, raising a glass of port in Porto, exploring Lisbon’s sunlit squares or enjoying the majesty of the Swiss Alps. Wherever your cruise takes you, there's always more to explore—and now, it's even easier to make your holiday last a little longer.
Add the magic of Switzerland to your Rhône river cruise
With our Lake Geneva and Golden Pass Extension, you'll wander Annecy's pastel canals, cruise Lake Geneva and tour the medieval halls of Chillon Castle. Ride a cable car to Glacier 3000 for jaw-dropping alpine views and the chance to enjoy the snow, then board the Golden Pass train for a fairytale journey through pine forest and mountain villages. And even with all this planned in, there's still plenty of free time to savour fondue, local wines and lakeside sunsets.
Unlock Portugal's past with more time in Porto
With our Porto extension, you'll wander Braga's golden cathedral, explore Guimarães’ medieval lanes and royal palace, and climb Porto's iconic towers for sweeping city views. There's plenty of time to lose yourself in bookshops, sip coffee in tiled cafes, or cruise Averio's canals by colourful boat.
Add Lisbon to your Douro river cruise
Don't let the adventure end at the riverside. With our Lisbon extension, you'll wander Coimbra's ancient university halls, lose yourself in the storybook streets of Óbidos and soak up Lisbon's sunlit squares and soulful fado. Marvel at Sintra's fairytale palaces and enjoy free time to sip coffee in tiled cafes and watch the world go by.
Spend longer exploring Budapest
With our Budapest extension, your adventure continues beyond in the Hungarian capital. Visit Hungary's Great Plains where we watch master horsemen in action and take a carriage ride through the endless Puszta and savour a traditional lunch to the sounds of gypsy music. Back in Budapest, we'll dive into the city's grand architecture, vibrant markets, and rich history. There's plenty of free time to wander at your own pace—whether that's discovering hidden cafés, exploring art-filled galleries, or simply soaking up the city's atmosphere.
Add an encore to your Danube river cruise: three nights of wine, palaces and music
With our Vienna extension, your river cruise becomes a true European epic. See the wild beauty of Neusiedlersee with a wine tasting lunch at a local vineyard, then settle into Vienna for three nights of imperial grandeur. Wander Schönbrunn Palace, sneak behind the scenes at the Staatsoper (that's the Vienna State Opera to you and me!), toast to the city's musical legacy with an evening at the Kursalon and enjoy time at leisure to explore as you wish.
