my expectations were pretty high my first cruise and at first they didn't meet what i had expected so i was really disappointed and it ruined the first half of the trip. then it got much better after i got comfortable w/ ppl and it turned out to be everything i thought it would be! you just have to make things happen for yourself. about the messing around part, don't do anything in places your parents would expect you to be in, like the disco or the pool area. i went to the bars during the day to do stuff and nobody else ever went in there so thats a good place to go. hope it helped!
