Passing on my experience for the next volunteer.
Louise skied on the carpets then one meadow chair run. As Louise likes some physical touch we skied side to side Louise touching my arm and my pole.
The challenge was to get Louise to look up, to see where she is going. I discussed with the caregiver, maybe the caregiver skies in front with a coloured card with a stimulating sign to follow, or try skiing backwards with her.
Have fun, we did.
