Riviera Travel River Cruises is offering up to $750 per person on 2027 departures in what it says is its biggest flash sale yet.

The deal is available on any new bookings made between September 16 and November 2, 2026, which must be booked by phone through Riviera’s reservation team.

Guests can save up to $750 per person on select 2027 departures, up to $500 per person on select 2026 departures and up to $250 per person on select 2028 departures.

Flash sale savings are in addition to the current promotion of up to 50 percent off select 2026-28 departures and can be combined with group discounts.

However, they cannot be used in conjunction with any other offer unless explicitly stated.

Cruise and Stay vacations are excluded from the promo and Deal of the Week departures already include the discount.

The cruise line recently opened sales for its 2028  itineraries, covering departures across the Danube, Douro, Rhine, Moselle, Main, Rhône, Seine, Dutch and Mekong waterways.
