Joseph, unless you’ve person send on a cruise,you can’t declare something treif based on hearsay. The Alaska cruise I was on had 150 passengers ( out of 900 ) with Kosherica. We had our own dining area so no treif at our table. The weather wasn’t warm enough for bathing suits, especially if you didn’t go to the swimming pool on the top deck. As Meno said, it is more expensive but what price do you put on having minyanim, shiurim and fresh food everyday, meaningful Shabbos programs nd being with 150 other frum Jews while being able to enjoy the sights of Alaska. Shmiras ynayim is a problem anywhere
