Jennifer, Yes, I agree with you completely, it's a sad fact that the Titanic seems to attract this sort of undesirable attention, we of the British Titanic Society have also fallen foul of it at times, so please, nobody think that this sort of thing is perculiar to the USA as somebody seemed to imply. What we do have to remember, however, is that the Company in charge of the dive is in the business purely for the sake of making money - they have never made any pretence of being historians or crusaders, and I suppose that if some clown actually wants to be married on the Titanic, they are unlikely to turn down the cost of a dive and more importantly, the media interest that goes with it, it may be an old cliche but there truly is no such thing as bad publicity!
My colleague will be aboard the surface vessel at the time, in preparation for his own dive, so I will report on the "wedding" and no doubt subsequent divorce!
