Conditions of use: to use the voucher, select the Christmas voucher option in the Payment Methods field of the camp registration form, then enter the unique code you received after purchasing the voucher in the Comments field. The voucher does not exempt the user from registering for the camp (registration and participation conditions are set out in the General Terms and Conditions of the camp in force at the time). The unique, one-time-use code will be sent by e-mail after purchase. The voucher can only be used once and will be permanently invalidated once used (it is not necessary to show it at the camp). Tip: it is advisable to register as early as possible to make sure there is space for the week of your choice!
