As a matter of fact, yes, we are going on a cruise. Why not? There isn't room for ALL of us under the bed!
I'm not a the cruisin' sort but if I were I don't think all the illnesses would dissuade me. Heck, I flew to Fla. and went to Disney and Universal during Thanksgiving week. I think my insurance company would raise my premium for that. LOL
My point, just makes you wonder. That is why I would be curious to know what was in the vials. If it were something non-fatal, it would take away the argument that the terrorist would not use a bio weapon unless it were deadly.
