I wish they would have left a note for their family and friends. This would have helped the investigation and closure to their loved ones. I agree with others this was a plan. I just don't understand why they did it the second day. Enjoy the cruise then do it on the last day back.
Kat, I think you are missing the point though...This was not a cruise they took for enjoyment. They planned it, and, and probably needed to expidite it quickly to keep their courage up. If we ever do find out, it may be that a note was left to the family at their home.
I wonder how many honeymooners cabins the steward nevers sees, or gets to go into,till a day or two into the cruise.
