Hello.
We went for the first time ever this February, so were complete beginners. Children were 8 and 6.
We went to Rauris in Austria on a recommendation from DHs colleague. It was perfect for us.
It's a fairly small resort, so it's easy to find your way back to familiar ground. I was content with doing the same couple of runs over the course of the week as it gave me the chance to improve my technique as the run became familiar. There were more runs available to me, but I was happy sticking to the same three on rotation.
We put our children into the Adventure Rauris ski school for full day lessons. We'd drop them at 0930 for a 10am start (though they generally started by 0940 because everyone was there). Then we'd meet them at 12 wherever the instructor told us to be, have lunch with them, and then hand turn back from 1-3. The ski school was excellent. Children pick it up really swiftly, and ours started as beginners on the Sunday morning, and both skiied a couple of reds on the Friday.
Rauris is a small village that looks like it came out of an Alpine story book. We stayed at the Schonblick Mountain Resort & Spa in a privately owned apartment that we found on HomeAway (now Vrbo, same premise as Airbnb). It was a five minute walk from the apartment to the ski school and main gondola lift. There are lockers near the lift if you don't want to carry your skis each day. We generally did that and just walked over in our ski boots. My children adapted very quickly to walking in ski boots for 7 to 8 hours a day. But your DC could always walk over in normal boots, you carry the ski boots, and just chuck the normal boots in the locker when you get the skis out (we did that once or twice).
We found the whole resort to be friendly, reasonably priced (even up on the mountain where you're a captive audience), well mainted and well organised.
And that wasn't a bad view over lunch either. Best family holiday ever.
