Never been to Lech but I spent 5 days in Tux, AT in early February. They got piles of snow this winter so your conditions are going to be awesome. Where we were, grooming was impeccable and the slopes were wider than the 401.
The vibe of Austrian ski towns just can't be beat. They make apres ski an art form. From 4-6 every day, people just party in a very positive, friendly way. Singing, dancing, drinking great beer. And it's all ages. No ridiculous 21 drinking age. Have fun. I'm jealous.
