Steve, how did it go?
If you haven't yet been to Val Badia, the area is great for beginners as there are plenty of easy blues; I am sure your girlfriend will enjoy it.
All ski schools are good, and most instructors speak English. I guess that, depending on when you actually go, it may or may not be possible to have group lessons. When I started there weren't enough adults therefore I had 1:1 tuition. Best money ever spent! And even if she does a couple of hours, that's enough for you to do a Gran Risa (black and red, the red is a great run), or a Vallon, explore Forcelles............
When I started I was doing an hour every morning with the instructor, and 2-3 hours on my own to practice while my other half was doing some "proper skiing", and in the afternoon he stayed with me on blue runs. The following year I started doing reds .........and the rest is history
so I am sure your girlfriend will soon be wanting to explore new slopes!
oh, and you were asking about free lifts........FREE lifts???? On the Dolomites????
