I would not recommend this resort towards the end of the season (march). Two years ago my wife and I went to soll, the attitude of some of the 'instructors' was pretty aweful. One swedish women lost half of her 12 student class by day 2 (of a week). Her attitude to someone struggling was 'you either want to ski, or you don't' before leaving half the class in difficulty. Four people gave up by day 3, 1 person never left the nursery slopes, and 2 others binned the instructor and went off on their own. As a medium level confident skier, I took my wife of on her own, then she finally started to improve and enjoy her trip.
The other resorts are accessible from soll, however beginners who are getting mobile, have to cross hard red runs to get back to easier routes. In complete cotrast the following year we went to Borovets in Bulgaria, completely different and friendly people.
