Helicopter Tour on Bora Bora Question

We will be staying at the Intercontinental Thalasso Spa for a few days in mid-June after a Paul Gauguin cruise. We want to take a helicopter tour with Tahiti Helicopter while there. It seems like a no-brainer to book a private tour with a resort pickup since the cost for the four adults in our party actually comes out to less money than cost of four single adults on a normal, 5-passenger tour. ($840 for private vs $263 pp).

We were thinking of adding the side trip to Tupai, but it doubles the price. My question is whether the 30 minute combo of Bora Bora and Tupai at $1680 versus the simple 15 minutes over Bora Bora is worth an extra $210 pp?

TIA, Bill
