We (2pax) have existing 3D2N snorkelling package with redang pelangi resort, and would like to add fun dives on day 2. But, Reservation dept do not allow for 1day fun dives advance booking, and only able to reserve if take whole 3D2N diving package. Is it ok to arrange on arrival? Will the dive centre fully occupied normally? Or anyone have redang pelangi dive centre direct contact?
