OK, this is the first time I've ever started a thread in AIBU so be gentle. 
Surely I'm not the only one that finds the whole 'let's dress up in period costume, eat fine food and quaff champagne while 're-enacting' the voyage' a bit sinister and ghoulish?
Could maybe see the point if it was for the descendants of deceased passengers as a memorial service, but the dressing up and 're-enacting it?!
Leaves me a bit cold just thinking about it.
(Not to mention the fact that bad weather conditions has been mentioned in some reports. Are they mad?! I'd have jumped and tried my luck at swimming to shore while I still had the chance!)
