I may be joining family on a Princess Cruise Lines cruise (Crown Princess ship) or a Costa cruise (Costa Fortuna)...but will need kosher food. (I've never done cruising but I understand most cruise lines are very accomodating.) Does anyone have experience with getting kosher food on cruises in general or w/these lines specifically? Is it airline food usual or something comparable to what you're paying for? If the "kosher" food turns out to be vile, are the cruise lines usually accomodating to double wrap fish?
