We have done private lessons in the past with our friends and family. First 2 times we lucked out, and got a great L3 instructor.
Later, I knew to have a look at who we get, including asking here for recommendations.
The $700-800 we paid a few years ago already had my friends in Europe gasping for air, but with 4 people, and some high quality instruction (not to mention getting more laps and finding the good runs on Presidents’ Day) It was worth it.
But $1222 (or an even worse cost for a group lesson) for a ‘Day’? No matter who the instructor is, that’s really hard to justify for something that’s just fun.
And then there is the fact that the instructors are are not making this.
I would have a bit easier time swollowing high rates if it was instructors charging that, pointing out they are spending time and money honing their craft, and have to cover the high cost of living in a mountain town in a small number of teaching days.
Only thing I'd add, as an instructor, is this: yes, it's expensive to take private lessons. So when you DO TAKE the lessons, what steps are you taking to make sure you're getting a lesson with one of the best instructors? Remember, the bright red, blue, black, yellow, or green jacket does not a great instructor make!!
It is foolish to pay for either a half day or full day lesson without having done the work of identifying the best possible instructor for your skiing needs. Almost all good/great resorts will allow you to pre-select the instructor of your choice. And believe me, there is a huge difference. Why would you want to be separated from $900-1,200 for the privilege of being with someone who just became a ski instructor? Or has only taught for a season or two? Of course there are exceptions, but the best instructors have been doing this for a while (like many years). And please, do not ask the 1-800 ski lesson receptionist "who's the best instructor?" Because the only answer you'll get is..."oh, they're all really really great".
Do a little scouting around the restaurants, bars and ski shops where you're skiing. ASK sales people, bartenders, wait staff, ski shop folks "who's the best instructor here for a beginner? Someone who's got a lot of fear?" Someone who wants to make a breakthrough? Ski towns are small towns, and everyone knows everyone. And they'll know who the best instructors are, and if you ask nicely...they'll probably tell you. Honestly, I know ski instructors who I would never recommend. The progress you and/or your kids will make skiing with one of the top instructors is 2x-5x more progress than you'd make with someone mediocre.
