As part of the policy, which is available on all new bookings, guests are able to transfer their deposit to another holiday of equal or higher value.
Riviera offers river itineraries on the Seine, Rhone, Rhine, Douro and Danube, and touring holidays to France, Spain, Italy, Germany, Norway and Iceland.
The policy contains Riviera’s price promise, whereby if the cost of a holiday goes down after booking, guests pay the lower price or will be refunded the difference.
Robin Shaw, Riviera Travel chief operating officer, said: "We’ve extended our policy as we want customers to have complete confidence when making a booking, and to be sure they won’t lose out if their plans need to change.
"Our customers have provided clear feedback that flexibility remains important to them, and we are absolutely committed to always doing the right thing by them."
