If there is a future payment in the system and you have a regular lesson time allocated, this time slot will be held for you indefinitely, if you continue to renew your lesson in blocks of four. If you do not renew your block of four lessons at the end of the current booking, this lesson time will show as available for booking by other students and will then be offered to any students on the waitlist. We will not be able to guarantee it will be available to you in the future.
