I waited a bit before posting my thoughts, as my initial ones were, shall we say, non-publishable. (Is that even a word?)
In any case, time hasn't changed my opinion. As an ocean liner fanatic, I'm rather appalled by this notion. Don't get me wrong -- I'm all for a voyage that honors the memories of those who perished tragic night. Promoting it as a near re-creation, implying a form of entertainment, is what bothers me. JMHO.
I hope that the lecturers have some true knowledge to impart. There is a great deal of misinformation out there.
