Members only: Travelzoo club members can save up to £1013 on six ultra-luxury river and ocean cruises. Each Scenic 6-star sailing comes with everything from flights to meals and drinks. Capacity is no more than 220 people per ship, so the staff-to-passenger ratio is high. Suites even have their own butler service.

The best part? Scenic's Enrich programme of private, cultural events is included in each itinerary. These range from classical concerts in Vienna and gastronomic tours of Sorrento to choir performances in a Belgrade temple.
