My partner's niece has sailed a couple of times on the Silver Wind and she has had great experiences, however, she is mid-forties and was "hit-on" a few times which she did not appreciate; but that can happen on a cross-town bus just as easily as it can on a ship or the bar at the Savoy.
But, be that as it may, I see you're in the UK. Let me tell you my experience with two VERY classy ladies from the UK whom my partner and I met on a Seabourn cruise. They are both widowed and sail frequently on Seabourn. They book early to get the best rates, they each book their own suites and have made a number of friends over the years. We will be sailing with them on the Seabourn Legend in April, 2008 doing the crossing from Ft. Lauderdale to Lisbon.
As past passengers with a lot of days at sea, they were given the opportunity and have already booked on Seabourn's newest ship, the Odessey, for the inaugural sailing in 2009.
I could probably put you in touch if you would feel better actually talking to another "British Classy Lady"!
