user: What are some good ski resorts for beginners?

assistant: Most ski resorts have excellent beginner areas (often called bunny hills), which are labeled as "green runs". These areas are also where beginner ski lessons are taught. In some cases, though, beginners prefer to go to smaller or less expensive ski resorts as they are not able to take advantage of the more difficult terrain on a larger mountain. In that case, a smaller, cheaper ski resort might be better for a beginner; these tend to be located on smaller mountains and can often be more convenient to nearby cities and towns, although the snow quality and number of ski runs is often significantly less.
