Niederau is good for beginners. Slopes are 30 metres from hotel. There are 3 drag lifts on the beginner slopes. It might be better to ski down at the bottom all week.
The problem with a gondola not going up, you can usually see just a 20ft drop. Coming down, you are looking at a 2000ft distance.
The fear of heights can be overcome in many, but not all cases. Familiarisation is a key factor. A prospective member of my family had this problem, so I worked with her to overcome her fear, and also with her skiing, she is now competent, and quite fearless. Had to do this before I could let her marry my son! :shock:
