It really depends on the type and length of programme. We would suggest a minimum of 15 people and a maximum of 100. Just because it’s a larger group doesn’t mean they wont get the same hands on experience as a smaller group as we’ll provide more members of our team to support larger cohorts.
When we work with smaller teams on an exploration and a longer programme (5-days) we have worked with groups of between 6 – 12 participants.
