The maximum team size is 7; this includes any leaders/helpers. We are strict about this, and any requests for larger teams will receive a polite no. This is due to the safety and enjoyment of all the players in a team. We also suggest a minimum of 3 people in a team.
If your teams have anybody under 14, they must be accompanied by an adult. However, if the team is solely over 14s, then we are fine with them going around independently, but the final say is with you as the group leader.
Each group registered should have at least one leader in attendance (either in the team or acting as a floating helper if needed). Please don't just send Explorers on their own.
