^I don't think we would have made a big deal if this was Carnival either. The truth is, it's just not that big of a deal. There are always cases of Noro going around on ships and even more cases off of ships. This is obviously a bigger than normal case (I blame New Jersey, where the ship came from!) but statistically it's still not like ebola death or something!
My parents just got off of a Royal Caribbean ship today with no cases of Noro. This certainly won't stop me from cruising, but it will remind me to wash my hands even more frequently because humanity is gross!
