You have NO IDEA about the amount of organisation it takes.
The amount of form filling you have to do. all the fucking Risk Assessments , all the poksy consent forms, collecting all the money. Answering all the stupid questions parents have. organising and running a parents meeting, which 20% won't turn up to and they'll be the ones who forget to pack the right equipment, or ask inane questions, or ask you ridiculous things like "Oh, can't the bus just pick up my DC from our house? it's driving right by us" or forget to send their child with their epiPen... or insist that they should be allowed to phone their child in the middle of the week, or send them with more pocket money than they're supposed to etc etc etc
And then you finally get them all on the bus at 4pm, with (hopefully) everything they need.
Then you have to keep 30+ 7 years olds entertained and manage toilet breaks and boredom and travel sickness for hours.
Then you arrive at the other end (let's say we're going to somewhere like PGL) you have to help them haul their luggage up, because some parents will have completely ignored the "ALL LUGGAGE MUST HAVE WHEELS" note
Then you have to get them to their rooms, and sort out bed squabbles, help the kids unpack.
Herd them to dinner, making sure they all eat properly - often helping THAT child who can't use a knife and fork, or is allergic to everything on the menu.
Then you finally get to grab your dinner, and still have to watch the kids.
Get them back tot heir rooms, get them into bed - helping them get changed where they can't do it themselves.
Makig sure they've all washed themselves and are actually in bed. Doing lights out and patrols. Finally getting to a quiet time, when you think "aaaaah, it's 11.30pm time for bed!" You get changed and some little child comes to your room crying because they're homesick. You escort them back to their room, when the other kids are now awake and setting off about they're home sick too. You calm them all down, say goodnight again. Crawl into bed. Wake up early, because they all have to be up and at breakfast by 7.30.
Get them all up, help them get dressed, do up more shoelaces than you should have. Discover a child has only brought wellies for the entire weekend. Traipse the over to breakfast, watch them struggle with the milk. Decide you now have to be the 'milk monitor' and stand for 30 minutes pouring milk. Wander over to your table, notice 6 of them haven;t got anything to drinks, send them off to get drinks. Watch one of them drop their cup.
The first morning they'll all have about the spoons of cereal and declare they've "had enough" you'll encourage them to eat more, because they'll be STARVING HUNGRY come 10am. No, they've had enough. Then you get them back tot he rooms, ready for activities. Where someone hasn't go a raincoat and it's pouring down. So you find a spare anything from what you've brought. You give away your jumper to the skinny little girl who's Mum didn't think she'd need one. You grab the first aid kit, the mid-morning snacks and herd them to activities, and sit watching them, for a bit, really wishing you had a cup of tea with you, and then one gets too scared and sits with you for the duration, whilst you try really hard to get them to do the activity. Then one of them "feels sick".
ALL OF THIS - and it's only 10am the NEXT DAY :( You're already tired, already done waaaay too much, and you've been with these kids a sum total of 16 hours, and you realise you've still got TWO MORE NIGHTS AND 2 and a half days of this.
by the last night, you could sleep through WWIII.
When you finally get back to school, and the kids are all being colleced - uyou're a zombie. You are so ridiculously tired and all you want to do is lie down and sleep. But you can't. THe kids are being collected. There's that one parent who takes forever to pick up their kid. You ring them and they don't answer, so you ring the second contact who has no clue that the child has even been away. Try the parents again, they finally answer and say "Oh we're shopping, we'll be there in a bout 30 minutes" you tell the child whoc is upset (because they're exhausted)
You wait in a carpark, apologising profusely with your eyes to your waiting husband, then eventually the parents turn up, you hand the kid over and go and die in the car, get home and collapse.
So, Yes. sorry the teachers/leaders/whoever deserve amedal and OPs like this SHOULD point these things out, because unless you've done it.
YOU HAVE NO IDEA.

But - we do it, because it's fucking amazing. The kids achieve so much, That one 'scared' kid, will eventually be convinced to go on the high-ropes and do it and come running to you jumping with joy about how she loved it and wants to again. You laugh a lot with the kids and leaders. You have special moments with all involved you get to know people on a completely different level. YOU find out stuff about kids you never thought possible. That 'naughty kid' will do something amazingly kind and be the most supportive kid there. They'll try and chase you with water balloons. Insist you go on the giant swing and cheer for you the loudest out of all the people there. They'll sing happy birthday to you loudly at dinner.
It's all worth it :)
