If the waves are too large or unsafe they will absolutely reschedule. You would need to bring your own hardboard and it will need to have a nose guard on it which you can buy down the street from Ripcurl (its about $8).
You can group people together, yes. Idk what their rescheduling policy is. The lesson includes wetsuit and board rental. Our group only used the soft boards; I’m not sure if they rent hard boards.
