What's the big deal? These six offers from Imagine Cruising take you to the most vibrant cities in the world. Each includes hotels, transfers, tours, and a rail journey that's easily at the top of every explorer's must-do list. 

Here are some of our favourites:

• Board the bullet train in Tokyo for a fully escorted tour of Mount Fuji, early in Cherry Blossom season. Then, depart for a 12-night cruise on Celebrity Millennium and take in the likes of Osaka, Kyoto, Hiroshima, and Busan. At £3499pp, this package saves up to £950 on similar trips we found.
• A summer cruise on Cunard's Queen Victoria, with stops in Spain, France, Sardinia, and Italy, is £5999pp. You'll then take an all-inclusive trip from Verona to Paris on the luxurious Venice Simplon-Orient Express.
• After a 14-night cruise around South America, travel all-inclusive through Peru on the luxury sleeper train, Andean Explorer. The train only has 35 cabins, meaning it sells out quickly. Among the many sights you'll get to explore on this £6499pp adventure are Machu Picchu, the Sacred Valley, and Lima.
• At 25 nights and £3999pp, this package includes a fully escorted tour of India, a cruise through southeast Asia, and an antique rail journey on the Shimla Express. Daily trips include walking in the Himalayas, the Taj Mahal, a jungle safari, and more.
