We are currently booked for 5 nights at Le Tahaa Resort in late March 2013. We are planning on diving while there and the only dive shop we have discovered is based at the resort. Their rates are significantly higher than those of the first two islands we are staying at (Tikehau and Rangiroa). Are there any other dive shops in the Tahaa/Raiatea area that offer a more competitive rate? Any help would be appreciated.
