The resort we are at only has the option of 5 day ski school for the kids
Highly unlikely, unless you're off to some tiny boutique resort balanced on the tip of a glacier, run by a polar bear and his little friends..
THeres one company who have a deal with the holiday co./hotel/resort.
There are probably tens to hundreds of other instructors and ski-schools at that location, you'll be able to get their details by .. googling the resort before you go, or by asking at the ski hire shop when you get there.
If you don't, you are going to spend the entire holiday sending children up and down the same 10ft of the icy lumpy bottom of the piste near your hotel, which your youngest may well enjoy but everyone else is going to have a shite time.
Or, you're going to go out, scare your kids stupid on the lifts, put them and others at risk of injury or worse.
You aren't even aware of these risks..
How do you use a button lift with a child?
If none of your children can use a button lift by themselves (And they may not even weigh enough to do so, if the lift operator will let them which they probably won't)...
How are two adults going to get three children up the slope?
Chair lifts - I mean.. just don't ffs.
You need ski poles in one hand, so thats yours and a kids, so one adult is going to have four poles, one is going to have six, or divide them equally if you've time.
Look behind you to see the lift coming, sit as it gets to you, not too soon or you're on the floor, being smacked in the head by the chair. Too late and its hit you in the back of the knees and you're not seated properly...
Oh but you need to put three children on the chair lift (if it will take five, it may not - some take two, three, four etc... thankfully the single seaters are a thing of the past I think)... so thats one of you chucking the smallest kid, one chucking the next smallest, at the same time as holding poles, stopping everyone falling over their own skis... but now who is getting teh 8 year old on...
Or maybe one adult gets on with some kids, the other with the one left... can you stop two children sliding under the bar (their feet don't reach the rests so they're pulled by the legs...) single handed whilst holding a fist full of ski poles?
Seriously.. don't. The number of ways in which someone could die are beyond counting!
I bet this is going to be your last ever ski trip if you spend the whole time side stepping up and down a few metres of slope with tired kids sick of falling over. Please don't die, and do look up hwo quickly children can become hypothermic.
