7โ. Go on a cruise across a large ocean โ anything deep sea really is a big no. Iโve seen Titanic, Iโve watched documentaries about what lurks beneath the surface, and I canโt really think of anything worse than being caught in a storm with 60 foot waves and then being shipwrecked on a piece of wood, with no drinking water, as my skin fries off, while monstrous sea creatures get ready to eat me.
