How many people will be in my group for Trailblazers and what's the instructor to child ratio?

Children are split into 2 groups: ages 7 - 12 & ages 11 - 15. There is a maximum of 10 children per group, in line with our instructor to skier ratio of 1:10. A minimum of three children is required to run the course. In the rare event a course minimum is not met, alternative tuition or a full refund will be offered.
