Ever since i saw titanic ive been scared of going on cruises and stuff.........?

SO TODAY I WANNA KNOW WHAT ARE SOME KINDS OF WAYS WE CAN SURVIVE IF OUR CRIUSE BOATS SINK, CAN SOMEONE PLEASE TELLME SOME WAYS?AND WHAT WILL THE LIFE BOATS DO IF WERE IN THE MIDDLE OF THE OCEAN?
With GPS and all the other safety measures on cruise liners today you have no fears concerning being found if your ship were to sink in the middle of the ocean. One of the first things they do on a cruise start is a life boat drill. The life boats are bigger than most small yachts today. They are sealed, carry more than 40 people, and you know where to go to get on yours should something happen.
Your biggest worry should be, according to reports from the last year or so, are food borne and person borne illnesses, but even then the number of occurances is much less than you would think.
Cruises constantly monitor the weather, so you go around hurricanes and such, although you might not make some of the ports you were interested in. They do try to make it up to you. Our cruise went very well, food was great and way too much, dinners were four and five courses, and there is great entertainment free each night. We sprung for a balcony room so we could see the ocean and islands, and it was well worth it. Spent hours reading and just gazing out to the horizon.
The only issue I had was the cost. They give you these personalized "credit cards" that get you into your room, buy you just about everything under the sun, etc., but you get your surprise the night before you dock when they shove the three or four pages of billing under your door, so if you plan on being frugal, get up and go get your own cokes, etc., or you will be charged for them, as well as these huge bottles of Dasani, etc., along with gold chains, duty free shops, and all the other promotions they run to sell stuff.
Bon voyage. Forget those worries.
