They are not a big company so I doubt that there will be many people who have gone on a cruise with them let alone win a cruise. If you have won the cruise ask them to put it in writing and then also call them to confirm the details.
Do not know if prize is legitimate but ship is definitely legitimate and is building up a loyal following. Friends travelled with them 18 months ago to the Black Sea and thoroughly enjoyed the trip. They have also travelled on the Hebridean Princess 6 Star Plus so know their ships. Ship is not new but very comfortable with good but not cordon bleu food. It is not the ship for a laugh a minute type cruisers. No bingo or production shows. It is run like the old Swan Hellenic line for more serious minded cruisers who are destination orientated. Guest speakers are professors etc.
We didn't exactly win a cruise with them but we got a Nile cruise free with a cruise we did with them and it was definitely bona fide....we had a wonderful week on the Nile with all excursions, flights and transfers paid for...all we paid for was our insurance...so I would expect you will get the same. It was our first cruise and the ship was excellent, no complaints whatsoever and from that moment we were hooked!!!
We have had six cruises with them, a lovely friendly ship. Not too big, but has all the things you would expect. Super lectures, often themed, we have been with BBC History Magazine 3 times. Even had Sir Edmund Hillary as a lecturer! Plenty to do. Good food, Met people who have been 15 or more times. We are going again in the summer.
