i am your age too, and i went on freedom of the seas in august. first off, i wanted to say that the ship is INCREDIBLE! you will never ever be bored.
also, as far as meeting people go....it is REALLY easy. just a bit of advice: ***try to meet people early in the week so that you have plenty of time to
***to meet people, go the the fuel dances/ activities, try to hang out in
the living room at nights, and INTRODUCE YOURSELF!!! it may seem
awkward, but everyone is in the same boat!
***take TONS of pictures. the more you take, the more it will help your post cruise depression (you'll have some). i didnt take many, and i sure wish i took more. it will really help you remember the crazy fun times you had!
hope this helped! you WILL have a great time on that ship, and you will meet tons of new friends. this ship is SWIMMING with teenagers, so you should easily be able to find people your age!
