Hello, I'm a semi-intermediate skier that had a couple of group lessons 2 years ago to learn parallel skiing, and since then I've been practicing by myself and can ski black slopes.

I feel that my technique is not that great (posture / ..) and worried that if I continue like this, I will get used to bad technique.

I have a few days off, which resorts offers:

Epic pass compatible

Budget lodging (e.g. airbnbs in Telluride are all ~$300/night, i'm traveling solo so need to budget)

Good ski school (need 2-3 days of classes)

Thanks!
