Primary pick-up point for the Conrad/Vaitape shuttle is the main pier for the shuttles leaving from 430pm onwards.
Believe the cost is 1500xpf per person RT for the shuttles leaving the Conrad up through 4pm. After 4pm, the cost for shuttles goes up to if I recall correctly 3000xpf per person. That is the RT cost, I'm not sure if there is a reduced OW cost starting from Vaitape but I would plan on 1500xpf.
