I work for www.CRUISE.co.uk. just to let you know Fred Olsen do offer female or male shared cabins. these would be at the twin price but you would obviously only pay for 1 passenger. hope this helps.
Dear kyle thankyou for your comment. i have been in touch with fred olsen their prices were more than any one else. aprox 1200pounds single or 1400pounds to share woth a stranger it doesnt make sense.
If u r a lady i will ask the wife if i can go .
