Fred Olsen Cruise Lines chooses Tui's Musement to power attractions offering

Tui Musement allows customers to discover ports of call “at their own pace”, the line said, after it finalised the agreement.

Guests can purchase tickets for thousands of attractions, including the Chocolate Museum in Cologne or a pass to visit the top archaeological sites in Athens, plus do activities such as hiring a bike in Amsterdam.

Stephanie Farrow, itinerary product and destination experience manager at Fred Olsen Cruise Lines, said: “While many of our guests love going on our organised shore tours, there are several who prefer the opportunity to head ashore and explore independently.

“At the same time, these guests may like to experience some of the attractions or museums available in various destinations.

“Tui Musement can help our guests not wanting to take part in an organised excursion, make the most of their time in port.”
