How can I cancel my ski school lesson? July 15, 2025 15:37 Updated Please email HISnowSports@vailresorts.com with any changes to your lesson. Related articles I need to change the date of my ski school lesson. How can I do that? I am not seeing availability online for the lesson I want to book. Is there a waiting list we can be added to? If my clothing has been damaged by the grease on a lift, do you offer cleaning services? If so, how do I access the service? Is there a non-skier viewing area for ski school? Where can lessons be viewed and booked for Hidden Valley?
