The remoteness of the islands and the mediocrity of the Internet connections in French Polynesia do not allow, realistically and reliably, to synchronize in real time the availability calendars of all diving centers.
Thus a delay of 24-48 hours is necessary to ensure that your booking is possible and that the diving centers or the providers have availabilities and can take into account your request.
Once you have completed your order and entered your billing information and validated the payment, your credit card is still not charged. You are informed by email that your request is taken into account and that a request for confirmation has been sent to the concerned diving centers or providers.
If all diving centers and all providers confirm availability then your booking is definitely confirmed and your card is charged. You will receive your final confirmation and your vouchers.
Otherwise, if some diving centers or providers do not have the required availability, then your order is confirmed excluding the centers and providers without availability, and you are informed by email.
Note that the limited offers and the Diving Pass are predefined and the confirmation delay does not apply. For these the confirmation is done instantly after the payment.
