Cruise is coming up this Saturday on the Grand out of San Francisco.  Each cruise I've gone on I get nervous that something terrible is going to happen and I'll have to cancel.  Sickness, injury, or some U-boat captain out there not knowing the war is over and puts a torpedo into my ship. 


Anyone else get those jitters as they get closer to the day? 


I do always buy insurance.  Hope I never have to use it.  Does the trip insurance cover my ship getting torpedoed by a U-boat???
