We booked a three hour private lesson for my son, who is 6 years old. The instructor was just like a parrot kept talking the instructions. Never, once bothered to show/demonstrate how it should be done, except when told to do so. Then, after burning few hundred dollars, we signed him up at North Star super stars program for half the price. Its a whole day program, instracutors do really teach instead of just yak.
Bottom line, donner ski school is not recommended.
