The majority of summer Scenic Group tours and cruises have had to be suspended due to Covid-19 pandemic travel restrictions.
Scenic Luxury Cruises & Tours and Emerald Cruises will suspend operations for land tours, river and ocean cruises up to August 31.
Scenic Eclipse sailings will be suspended until September 30.
The group said it was committed to protecting agent commissions on bookings for cancelled cruises that have been paid in full and for the total amount of future travel credits.
Booked customers are being offered a flexible future travel credit valued at 110% of monies deposited on any affected river and cruise booking and 100% on land tours.
The credit can be applied to any new or existing booking across the portfolio of brands through to June 30, 2023 and can be transferred to another guest.
Should a guest be unable to travel by that date, they will be given a refund.
UK managing director Colin Downing said: “Our top priority is to ensure that our guests and employees are able to travel safely before we resume operations.
“Although we have seen some easing of national lockdowns, the restrictions on travel still vary considerably from country to country and it is sadly impossible for us to operate our scheduled departures up to 31 August 2020.”
