Jackie Martin, director of marketing and sales at Fred.

"Whether you are looking to escape for some sunshine as the cooler temperatures draw in at home, or if you want to look forward to a new experience or adventure in the later part of the year, I am sure there will be a cruise to tempt you. All of our 2022 cruises set sail from a regional port within the UK, meaning you can enjoy a stress-free check-in, avoiding long queues and delays.
"Plus, with up to ?100 per person to spend on board if you book this week, you can really make the most of your time with us, from relaxing treatments in our spas, to delicious meals in our specialty dining restaurants or using towards immersive shore tours in the destinations you visit."
