i have been away for a few days and just saw this thread -- my perspective/experience:
i am the oldest, my sister is the youngest, with my brother in between. when i was a teen, i was terrible. i had mood swings (we later found out this was due to PCOS and could have been better controlled), terrible temper that i would take out on my sis/brother and i was a total brat to my parents. i felt that nobody understood what i was going through, the pressure i was under (i put that pressure there myself), the demands of my life etc and i took most of this out on the people in my immediate vicinity (ie parents/siblings). in public i was an angel, had steady part time work from the time i was 12, great grades, outgoing, friendly, sociable etc.
at the time, i knew what i was doing to my family was horrible. i would yell and cry and get really mad and storm out of the house to go to work/school etc and then cry all the way up the street to the bus because i hated being like that and hated the way i was treating my parents.
it was a terrible time, and i'm glad to say that the mood swings passed and my mum and i are incredibly close (and in fact always have been).
my sister (6 years younger) started hitting her mood swings right around the time that i was finishing mine up. my poor mother. to this day, the 'silver highlights' (grey hairs) she has she attributes to me.
re: the boundaries/allowances thing.
my dad was an only child and his parents were very rigid with him. my mum was the youngest of 3 with 2 utterly spoilt older sibs, so we had a pretty strict childhood. growing up, if we were going somewhere, we would have a family talk before we left. it would be explained that we were to be well behaved, polite, etc. if we wanted something, we would ask once, politely and not whinge, whine or chuck a hissy fit. if we were very good, we would be provided a souvenir or treat or present of some kind (bribery works!).
getting into our teen years, going out was an extension of that.. we always knew to be polite and respectful in company. we were taught to respect our parents and to abide by their wishes as their word was law under their roof. we always got the phrase 'as long as you are under my roof, you will respect our wishes - once you have your own house, you can choose what to do then'
going out with others was pretty restricted in my house. my parents explained that they were not comfortable trusting my welfare to people they had not met before. they were very clear that until they met and trusted someone, that person was not going to be trusted with my welfare. my first boyfriend (at the age of 16) once wanted his older brother to drive us somewhere and got on the phone to my mum to make sure it was ok. she said no, but he told me that it was either his brother or i walk home (we were on the other side of the city, and i had no money etc) so i got in the car. his brother sped, drove like a maniac, almost crashed several times etc. when he finally dropped me off at home, i promptly broke up with said b/friend, went inside, explained the situation to mum and had a big old cry. after that, i carried emergency money and was given phone money and a mobile phone that i was allowed to 'borrow' when i was going out, but it was for 'emergency use only'. the idea of using it to call friends or text was so anathema

ahh, the good old days. only 12 years ago....
my brother was given more leeway to socialise/go off alone than i was, as my parents felt it was safer for a boy to be out alone than a girl. double standard? yes, but they explained it to me before i went out, explained their reasons for it etc. they were very open and honest and communication was a big part of our relationship. if we didn't like something or disagreed, we would all sit down and talk about it -- why the decision had been made, what we were feeling, why we disagreed etc. in the end, compromise would be reached.
because of that communication, my mum had a deal with each of us 3 - if we began having $ex, smoking, drinking, got a tattoo etc, we were to tell her. if anything happened, if we got into trouble etc, we were to tell her. no judgements, no recriminations, just an FYI.
as it stood, my brother took his first drink at around age 19. mine was at 18. my sister was at age 16. none of us have been drunk or hungover ever. my brother started smoking the day my grandfather died, and quit one year later. we haven't used drugs and my brother got a tattoo when he was 24 and told mum about a month later. he had body piercings at 18 which he told her about. most of it, she chose not to share with my dad but we all escaped our teenage years relatively unscathed.
my sis still has the mood swings. if something happens to us kids, our first call is to mum. that communication policy has stood us in good stead so far.
re: taking your DD on the trip and her moods -- my recommendation is to sit her down and talk - explain this is the last possible trip for a while and you want it to be special. explain everyone gets frustrated, angry, irritated etc but as adults you learn to deal with it in ways that don't make others feel bad, and if she is having those feelings, to discuss it with you or discover some way that she can express those without bringing everyone else's experience down etc. hopefully this will result in her managing her moods so that everyone can just experience the good of the trip and not have to manage her moods all the time
