The maximum number of participants that an instructor will take on one lesson is usually around 6 - 8 people. However, this will vary slightly between schools and instructors and will depend on personal preference and what the instructor's insurance will cover.
Depending on the school or individual instructor, there is a small surcharge per extra person booked into the lesson. This will be automatically adjusted on your booking form and will vary across the board. A typical example of this is €15 extra per person, per hour above four people.
Please note that every participant must be of the same ability level. In the case of mixed ability participants, the lesson will be taught at the lowest level.
