Yes, absolutely no problem, but of course you should contact us as soon as possible if the situation changes since you ordered your membership. Until the first visit, your membership is considered unstarted and its start date can be adjusted. There are 2 solutions:If no future lessons have been booked yet, then we cancel the membership and simply re-attach it from the new start date.If there are reservations made in advance, it all depends on their quantity: if there are only a few, then we ask you to cancel them and then, according to the first solution, we cancel the membership and open a new membership from the new date. If there are enough reservations made in advance (only from a later date than the one on which the membership was ordered), then we simply extend the membership so that it is valid for 30 days from the first reserved lesson.
