Uniworld Boutique River Cruises is offering a 100% single supplement waiver for solo travellers across 17 itineraries departing until the end of June.
A total of 78 departures are available with the solo supplement and bookings must be secured by February 29 to qualify.
Included is the line’s seven-night Brilliant Bordeaux cruise on ship Bon Voyage with calls at Cadillac, Blaye and Libourne.
Solo supplements are available on departure date in March, April and June and prices start at £2,549
A spokesperson said: “River cruising in general is ideal for solo travellers because smaller numbers make it less intimidating than the big ocean liners, but there is still a good crowd of an average of 120 guests on board with whom you can easily strike up conversations over dinners and activities.
“Everything is included so you don’t have to worry about making your own arrangements but you also have the flexibility to opt in or out of experiences.”
