Planning a trip on the Sensation in Jan. How is the ship and is there a lot of games and stuff to keep you happy while at sea so much? Taking 2 thirteen year old girls and was wondering if on Jan 2 a lot of other teenagers will be one boat. They do not go back to school here until Jan 6. They will only miss one day of school. Undecided on Sensation or the Imagination. Does one you think have more teenagers than the other????
